i created an iMix which is available on the iTunes Music Store to check out quick links to songs i’ve played. you can check it out here.
keep in mind this is very preliminary because, although i buy tracks from the store regularly, i usually convert them to mp3 to get rid of the DRM immediately thereafter. of course, Apple doesn’t like this and refuses to publish it in my iMix unless the track is in its m4p format. this doesn’t suit me particularly well, but you gotta work within the rules of the game, i suppose.
feel free to email me to add some suggestions of what i may have forgotten.
