I got this problem with my last computer as well.
For some odd reason, I cant see the artist and album name below my mp3s, or even when I hold my cursor over them. Normally if you hold your cursor over an mp3 it'll show "Artist, Album, Year, etc" but mine just says "Type" and "Size."
How do I fix this? It's really annoying.
EDIT: It seems the problem is only happening in My Music folder, and all sub-folders in My Music. :-/
