There is now a link over on the right-hand menu bar to an iMix I submitted for iTunes. If you have iTunes installed on your machine, you can click on the link and it will pull up my iMix.
I also currently have one other iMix there and I plan to submit more. Unfortunately, some of the songs in the iMix either aren’t available on iTunes or otherwise don’t come up, so you don’t see the whole thing. I may soon devote a whole page to the iMixes and detail the missing songs.
Once in iTunes, you can click on “iMixes by this user” to see the other iMix, which is actually the first part of the compilation linked to.
