Need help with iTunes and album artwork!

[Tau]

I use iTunes version 9 and my problem is that most of the songs that are not on the same album, not even released in the same year, but only from the same artist have same album artwork. For example, Delusions of grandeur have same album art as New York city boy single! And even when I put correct album art on Delusions of grandeur (Get Info-Artwork) it still has New York city boy album art. Can't change it at all! Please help,as I like having album art,but correct ones! I use Windows 7.

Delete any downloaded artwork and add it back manually.

I didn't have any downloaded artwork, but figured it out.
