What a ridiculous suggestion! Delete music just because it doesn't conform to a particular software program's idiosyncrasies? I'm not going to delete over 6,000 songs, many of which are rare and impossible to find, just because they're not part of an album. Many artists are "one-hit wonders", or only released several singles, but no albums. Many others have famous songs that were only released as singles and were never included on albums. So your idea is to delete everything that's not part of an album?or you can do what i did and just go through and delete any song that is not part of an album. ...
I was having the same problem.
I believe that if you merely enter in the artist in the "Album Artist" field, it will then group them together.
The Album Artist field is populated in all my library. That doesn't correct the problem. iTunes still creates a separate "Unknown Album" for each song, not each artist.For me, setting an "Album Artist" for all songs from the same artist has helped. Thus all songs without an album by the same artist are put in the same "Unknown Album".
