Repost: Library Columns displaying 0 time, 0 bpm, and 0 size while playing song in player
*IF THIS POST IS A DUPLICATE, PLEASE KEEP THIS BODY OF INFO OVER THE PREVIOUS AS IVE EDITED THIS ONE TO READ WITHOUT TYPOS*
I have been digging through your forums which btw, are amazing. You obviously care and this is demonstrated when one spends a lot of time reading your forums. But this problem continues to elude me. I have 18560 tracks total. My library is comprised of primarily .aiff,even though i use a PC. I selected this format because i was curating my 20 year long dj library into something i can use for the next 20 years. I decided to only download .aiff over all other lossless formats because it contains metadata in the file, or i guess .aiff is a folder CONTAINING the audio track itself....the music data, then im guessing headers, footers, and all musical tags.
I do still have a handful of .wav, but those i can convert in itunes, so i try and convert them all so i can have one format for all dj music. Some of my oldest music is in .mp3, .m4a, and a handful of .m4p. M4p is protected i understand, and these appeared after i uploded my existing purchased music to apple music long ago, and then lost my local version, and redownloaded my music from APPLE MUSIC where i discovered a large chunk of music i paid for originally, was converted to .m4p when redownloading from APPLE Music.
I have removed the .m4p tracks to a folder on C drive. My music is all contained on a drive that for some reason keeps getting reassigned a drive letter. Its an internal m.2 NVME drive. C=system, D=docs (both on one physical drive), E=Video, F=Photo, G=Music and ive added a couple more USB drives. It is when adding and removing these USB drives that are external drives that windows renames drive letters, even when i specifically CHOOSE drive letters in Windows Disk Management. SO perhaps this is a part of the issue? Ill include a screenshot of my current DRIVE LETTER ASSIGNMENTS.
My total library is being transitioned to a single folder for all music. This advice comes from watching dozens of hours on library management, and decided a single folder with no nested subfolders was best because its hard to id duplicates which is a big problem in my library.
The main reason ive chosen your software is the deduplicate feature and the ability to export to all other dj software platforms. The ability to manage tags and library meta data is a bonus, but it seems the file management meta data editing feature......well, maybe its not visible in Windows 11 23h2? Ive been trying very hard to get my library readable in windows, or at least, to display more metadata then the extremely limited amount of data it will allow .aiff files. I also observed many .aiff files are actually .aif files which my understanding is because its a version of .aiff files created BY WINDOWS or IN WINDOWS.
My library is finally all in one folder. Now just before trying your software, i had been attempting to get ahold of my wild library meta data issues and of course, the duplicates. So Mixed in Key has been used because it allows writing meta data (i havent experienced in any software) AUTOMATICALLY by batch in one of its features.
i have been trying to align my whole library to be displayed uniformly in any software i use, on any computer, no matter what my income levels. I discovered the danger to my library by storing in clouds which is what i did for a long time. SO this long battle has been 2 years, and ive been trying different dj software, Rekordbox, Serato, and DJ Algoriddim, Engine. Im currently without a controller and am trying to decide which controller I INTEND TO USE once i resume employment. "No income" dj library management is incredibly difficult in windows with mostly .aiff files. I failed to mention my library is .aiff, .aif, .wav, .wave, .mp3, .mp4, .m4a, .m4p, and .flac.
Ok thats all the background data i think might be useful. Heres the questions:
Question #1. Why are these playable, demonstrate a wavform, but register BPM, TIME, and SIZE as ZERO or display nothing and on most files the section to scan bpm says BPM unreadable?
Question #2. I'm wondering if its safe to delete these zeroed tracks.
Question #3. what are these tracks and how do i fix this using your software?
Question #4. Is there a way to batch edit certain tags using your software?
Question #5. Is there a wayto edit audio file tags and metadata in mixo that displays in windows?
Question #6. How do i use your software as my library management software using .aif, .aiff, .mp3, flac, .wav?
At one point I fully deduplicated using your software, but later found a hard drive with a ton of music that i forgot to include in the first batches of files your software analyzed. I added this folder and my previously curated 13000 ish track library (your software helped me deduplicate from 23,000 tracks down to 13,000). Then i added this SSD just to be safe i had every single song once in this single music folder drive. Now im back up to 18,600 and im noticing for the first time these tracks with zeroes everywhere yet somehow is still playing the music in your player and any edits made dont save, even though youre allowed to open the editor and allowed to type edits in, and allowed to click save.
In your deduplicate function, you give some amazing data that help you select which tracks to keep. I believe the most important columns should be bitrate, bit depth, sample rate, length, size, bpm, key, cues, playcount, title, and filename/file location.
Ive been finding these phantom tracks only visible in your software with the zeroed columns. As i purged my library using your dedupe and was sending valid copies of my music to the recycle bin, I was doing so based entirely on your limited column tag metadata visible in the dedupe feature. You ask us to chose which copy to keep with helpful data choices visible, but many other critical choices of data to review before deleting forever are not listed or able to be reviewed.
Your support is better then most (bit depth is nice here because some dj software only allows 44.1khz and not 48khz). As im finding all these zeroes, i would have deleted zeroed out metadata tracks over others if i could see those specs.
Windows DOES NOT display all meta data for .aiff and .aif files in its file explorer columns, even though .aiff files are supposed to attach meta data to the file. .Wav files are just audio and cant contain metadata, even though windows DOES display their metadata in its file explorer columns as well as .mp3, .mp4, .m4a, and .flac.
Im not thrilled that as dj's, we have very little free library management that isnt incredibly complicated open source tag editors. I dont mind paying for your software because if you become limited by employment, the free version still alows you to use it for grooming ones library. HELP!
The same question 
Hello and thank you for the long and detailed messages!
There's plenty to dive into here, but let's start with your questions;
1. How did you import your tracks? Normally, for importing tracks directly, or through M3U or Serato, MIXO will analyse your tracks and read the metadata from the tags. For most other imports the data comes from a database.
If your metadata is missing, either MIXO could not analyse your tracks, or the data was not in the database.
If you've imported tracks directly into MIXO it's unusual for MIXO to not be able to read the tracks. However, there are all sorts of logs attached to your message which indicate you've done more than just import your music - for example; some of the failed info relates to updating track tags.
2. I recommend adding the FilePath column to the track-list and check where the tracks with no metadata are located. This might give you some indication about the issue, or if they are safe to delete.
3. As above.
4. Yes, you can select, right-click and batch-edit Track Info for up to 1000 tracks at once.
5. Yes, you can Export -> Update Tags to write new metadata etc to your tracks, which should display in Windows explorer.
6. MIXO supports all of the file types you mentioned (.aif, .aiff, .mp3, flac, .wav) so you can play your tracks directly in MIXO, create playlists, import/export to other DJ software. The killer feature is sync - MIXO uploads your tracks to your connected cloud storage and syncs your library to the cloud so you can manage everything from your phone or additional computer.
I hope that helps!
