When I import a CD album that includes songs with co-artists, the album is saved once with all of the songs with the main artist only, and then one album for each song with a different co-artist. How can I avoid that or fix that result after the fact.

Question

When I import a CD ablum that includes songs with co-artists, the album is saved once under the album name with all the songs from the main artist; then each song with a different co-artist is saved separately under the album title with just that song.  Who do I prevent that or fix it after the fact, i.e., copy the single songs to the main album?

Answer 1

Why aren't songs with the same album art grouped together? - http://support.apple.com/kb/ts1468
Compilation checkbox is under options tab when editing multiple tracks at once.
