internet radio for free

I went to a customers' place the other day and as I was fixing his computer he mentioned to me that we were listening to an internet radio station that he only has to pay 15 dollars a year.  I told my customer to check out shoutcast radio at http://www.shoutcast.com/  It has every genre you can imagine: rock, 60s, jazz, classical etc and it is FREE.  My client was a bit miffed that he paid for something you can get free but he assured me that he was not renewing his subscription to his radio station...so check out shoutcast for very clear streaming radio for FREE
