For those of you who are Radio Freqs like myself, you're gonna love this site.
"They" have packaged radio stations and presented them in ways that make listening on-line a very simple thing.
Find a format or city or station you want to listen to, from anywhere in the world, click on the "Listen" button, and it loads a player that will quickly and easily play the stations feed, if it has one.
This is something the Internet has been in need of for a long time.
