Hey there. For all of you with iTunes and an iPod looking for an easy way to get your hands on some cool tunes, I have compiled a list of progged-type bands that surprisingly enough are available for LEGAL purchasing and downloading on the iTunes Music Store. Many thanks to the great progscout 
(AKA Pinkie) for his list of progg acts, some of which I actually found. Feel free to add to the list.
