So it's both. What's the problem with that?
I think the biggest advantage of having per track credits is that the resulting album credits can be autogenerated, which again could be used to allow visitors to set their list display preferences. I'd prefer to know all albums to which a composer contributed new compositions. Others may prefer a list were new versions of a composer's music are featured. Again others may prefer just to see a list of new arrangements of a specific musician etc. etc. Trying to achieve this kind of flexibility by manually adding specific tags on an album level seems like a waste of time to me due to its inherent inflexibility.
