Does anybody know how songs hold genius info, and does changing a track name affect this?
Originally, I assumed each track had some sort of metadata which said how it should be turned into a genius playlist. This way, only songs with entries in gracenote would be able to make a genius playlist.
However, the other day, I bought an album, and when importing it into iTunes, fount it had no gracenote recognition. I added all the details (artist, track name, ect) manually.
A day or so later, I discovered that a couple of tracks could make a genius playlist, even when they weren't recognised on gracenote!
So now I assume that the data is held using the details that the track has (artist, genre ect.).
My problem is, if the data is stored by the details a track has, will changing the details remove the ability to create a genius playlist? I have many tracks where I have changed the details (ie. "Track" by "Artist feat. Artist" to "Track [feat. Artist]" by "Artist")
So does anybody know how this data is stored, and will it affect my genius playlists?
