Artwork Confusion

[Khashayar jan]

Its been a week that i have a problem with my ipad and i hope you guys can help me (please).
About 40% of artworks of my songs are confused
For example : the picture of song A is on song B (or even picture of a video is on a song and vice versa)
What should i do???
Ive copied a video by iPad Mate
Could this be the reason
Please help me
And please don't say i should Restore my ipad


Thanks a lot

(sorry for my english)
