I sort of help on a live365 radio station for a message board im on...its like 250 a year I think for 300 MB worth of storage for the station, which is roughly 300 songs....
Ive done shows on it before...the interface is really easy to set up, both to run regular rotations of songs and to do things like concerts...the guy who "owns" the station does regular theme shows every month, I've done stuff like concerts...all in all it's a pretty good experience, and something for the big yawn site would be well worth listening to
