If you have iTunes 4.5, you can go and check out my first iMix. It is a work in progress.
Note to Steve Jobs: It’d be nice if the maker of the iMix got some store credit for each purchase of songs out of the iMix. Of course, that would mean that iTMS would have to differentiate between a purchase made out of a mix and one made from the store at large, but hey, you’ve got a lot of smart people out there in Cupertino… I’m sure they can figure it out.
