CD Art Display is a great program. If you failed at the tutorial I posted on how to change your MSN picture to your currently playing album artwork, this program will do it all for you. It also displays the current artwork and info for the currently playing track, finds artwork, lyrics, etc. The display is skinnable, and can look amazing. Head over and download this program. I love it.
The lyric functionality doesn't save the lyrics to iTunes directly (as far as I know). So you can still use iTunes Lyric Downloader for that. And if you want to fix your track information so it looks a bit better when you display it in CAD, try this.
(This also means I'm ending all my work on iTunes Displayer, since it's crap compared to this program.)
