I'm sure we all have some songs in our collections that appear on an LP, but then it's also the B-side to a single, or it's on a compilation, or a soundtrack. Sometimes, you might want to listen to it in the context of the LP, and sometimes the soundtrack.

You could have multiple copies of the song in your library, but if the recording is identical, why not sort one track into multiple albums? Is there any way to make this work in Gmusicbrowser, the way you can select multiple genres?
