Here is my take on the "Source" versus "Album" controversy:

The word "Source" is more correct, but I dislike it.

For me, an "ALBUM" is a unified work. A single entitiy, made up of a group of new songs by a single artist. For instance, Rush:Moving Pictures is an ALBUM.

However, sometimes the songs from an album can show up in other collections. For example, a Greatest Hits collection, or a movie soundtrack, or a K-Tel Rock Anthems Of The Eighties CD collection for only 29.95!!! ORDER NOW! OPERATORS ARE STANDING BY!

I think if you ripped the track Tom Sawyer from the Moving Pictures album, then the term Album is correct. However, the term Source is also correct, since the source for that particular copy of the track was Moving Pictures.

But if you ripped the track Tom Sawyer from the K-Tel collection, then the term Album is completely wrong. The K-Tel collection is merely the Source of the copy. The original Album is still Moving Pictures, but your ripper software drops the K-Tel collection name into that field. So, for that case, only the term Source is correct to describe that field.

Because the software doesn't know whether the song was from the original Album or from a collection, then only the term Source can be correct in all cases.
