Usability, iTunes and my music
Apple should incorporate some of the social/community networking tools we’ve become addicted to, including del.icio.us, Digg! and Flickr, into the underpinnings of iTunes.

Imagine being able to free tag your own folksonomy within your collection. Rate not only the songs themselves, but the artists, albums and genre’s. Mix this in with the Smart Folder concept, and you have some powerful organization and sorting tools for your ever growing music collection.
So how about it Apple? Free tagging support, with some social musical bookmarking built-in, similar to your play lists on the iTMS currently. The ability to freely rate many different categories and allow more freedom for end-user hierarchies. Anyone? Google?
