I recently deleted in library only an album or playlist in Windows Media Player. I cannot restore it back to WMP. It's still there in my actual My Music library, the folder with the soundtracks. I wanted to have each track covered with an album art, but I got frustrated for unable to change them all. So I removed the album from WMP and now I can't seem to see it in WMP even after placing a new album of the same title. FUUUUU!!!! Edit: Problems solved. Album art successfully added with new refreshed list.
