JUST FOUND THIS INTERNET RADIO SERVICE-200 PLUS STATIONS FOR IPHONE, IPOD-TOUCH, AND IPOD- BUT CAN TRY ON YOUR COMPUTER http://flytunes.fm/  

while the concept is good...

the idea of an all-Rush radio station is what drove me away from radio and toward ipod in the first place. i'l keep my all A3 channel, my all Decemberists channel, my all Magnetic Fields channel, flytunes can have Rush and the Grateful Dead. although i will have a hit off the deadheads' bong, thank you very much.
