First Released Year
We as DJ's are unique in that we don't really care what year an album came out. A best of the 80's album that came out in 2020 doesn't mean we want to play it at a 20's party.
So for the songs on that album what we actually want is an earliest released date.
Please mixo, add that functionality.
When I play Sweet Dreams, I need it to have the single release date, not the greatest hits date, or the release date of the remix, or even the release date of the DJ compiliation.
