Is there a way to change the default album artwork, whrre there is no real one, to a picture that i want? so like all the songs that i dont have artwork for have the little music picture for the artwork. I want to change that picture to something that i choose. Is that possible? thanks.

Yes it is, In any SSH or even iFunBox for PC
-Applications->MobileMusicPlayer.app->replace "noartplaceholder.png"

Edit: then Respring

thanks, im going to try it right now.
