If you, like me, have lots of MP3 albums organized in folders with the album covers, XP has this cool feature that you can see the album covers in the parent folder if you choose thumbnail view. Default you will only see a mini preview of the cover, or you can select properties and select a folder picture and you will get a full view.  The tweak is that, if you rename the album cover files. etc Jay Z-Blueprint.jpg  to FOLDER.jpg, the album cover will automatically maximize so you don't have to go and select the folder picture.
