If you want to experience your iTunes collection away from home and in a whole new way, SonicSwap may be a useful service for you. Simply upload your iTunes library file to the site, and it will provide you with video playlists of your music to watch and listen to free and legally. And the nice thing is, you don't have to upload each individual song---just the library xml file. (Compare that to Anywhere.fm).
