Your MP3 problem is due to album name in ID3tag. Whether all with the same name or empty. If empty, stock player will treat it as an unknown album. Meaning it will still use the first song of the pack's album art for all the songs and it will just ignore others album art. In your case the first song is by Adele hence all your songs will only display the same album art. If you tap on
Albums, you should only see 1 album.
3 Ways to fix this MP3tag issue
====================
a. Simplest way, buy an alternate player such as PowerAmp as suggested.
b. Edit each album ID3 tag manually. Make sure all have different album name unless they are from the same album. Clear Media Storage data after editing.
c. Flash to CM7 which I'm using now without such problem whether the MP3 have the same album name or not, it will use the default MP3 album art. Only for non-G.

Hope this is clarify those MP3 album art display issue for those having the same as well.
