Album Art Problem

[scrobisch]

When I copied my music from my PC to my Phone, I didn't realize that a stupid picture was included in the files, and now my phone set it as the album art for all of the songs that didn't have art already associated with it. So I deleted the music files and the picture file from the phone, and re-copied the music back onto the phone. But the phone still shows the same picture as the album art. I know that I can sit and click "Update Album Art" for each song, but not all of the songs have album art as some are from movie or video game soundtracks, and others are Singles from amateur musicians, and the phone can't update its album art because they don't exist. All I want is a generic image for all the songs or nothing at all, what do I do? Thanks for the help
