"Share any song in your iTunes library and download any song from your friends' iTunes libraries over the internet with Mojo. Essentially, Mojo makes sharing music with your friends through iTunes wildly simple, from its simple interface to its brilliant implementation. If you've ever used apps like previously mentioned ourTunes to download music from shared libraries, you have an idea of what Mojo does, bu you should still prepare to be amazed."
Made even more pleasant for me because I get to lord the usable technology banner over my Linux friends once again. Get some usability, geeks.
