iTunesNowPlaying is a plug-in for Itunes for windows that displays track informations in a notification skinned window. Informations displayed are : cover art, track title, artist name and album name.
I used this for many, many years when I had my 32-bit PC. Unfortunately it does not work with 64-bit iTunes though. Here's hoping the developer updates for 64-bit.
Using iTunes 10.7 (artist grid view was stupidly removed from iTunes 11) on Windows 7 x64. This plugin caused iTunes to crash every time I closed it or tried to play a song. May work on older versions, but not anymore.
