It's funny cause g00ns are actually a clan themselves. Silly script kiddies. I also remember back in GTA3:MTA 0.5, they ddos'd the now [KFC]vtec's Challenge Server. It went out for about a week before it got ddos'd once again forcing vtec to shut it down completely
If synched radio stations were ever to occur, I highly doubt that 'User Tracks' would be synched. Everyone has their own music and I doubt someone with lots of rock music would want to listen to hip hop, and vice versa.
