How do I combine Albums?

Well it all depends on what kind of CD is it cause if it's a soundtrack Ты should click right on a track hit "get info" and on the info tab make sure the Album Artist is marked as various and look and see that the "part of compilation" box is checked.

If it's an artist CD make sure the name of the artist is in the "album artist" and that if there is a guest performer put them in along with the other "Artist" and make sure the "Compilation' box is not checked.

Best of Luck
