Can I get some help with my album art?

[Dalton Kinley]

I need help with my album art.

Okay, so i'm picky with my music tags and i'm downloading all the right albums rt for my music. and since most of the songs are singles, i out the album as "Single". then i went to my player to make sure it was working out good, then i noticed that they all had the same album cover! so i tried emptying the a;bum field, and they once again had the same album cover. any ideas on how you can help?
