When I first wrote the subsonic provider, I took the maximalist approach to associating artists to tracks and I associate the artist ID listed on the track as the one. This was fine for my collection at that point because I had hand created most of the tags and artist for the track would almost always match the one for the album.
However, now that I have run my collection through beets the track artist string tends to contain the entire list of folks on a given track. So if I have an album by Atmosphere, I also see an artist entry (in the Artists view) for 'Atmosphere feat. deM atlasS' and 'Atmosphere feat. Aesop Rock', etc. I am conflicted about if this is a problem (though a user in #subsonic does think so). On one hand, when I click on Atmosphere, I want to see all the albums and tracks for that group. But I get that other users may want to have tracks sorted by the artists on that particular track. My question, now that I have rambled about it, is: is there a consensus on the 'right' thing to do here?
