I think you're approaching this from the wrong angle. You'll want to put 
the data at the highest level at which it changes.

i.e. If every song on an album is always the same year, put it at the 
album level, however, if it changes from song to song on a particular 
album, then you want it at the song level.

Year wouldn't ever apply to artist I don't think, unless they're truly a 
one hit wonder. :)
