It's out on official firmware. Just update to the latest firmware, then add Internet Radio 1 which does Shoutcast. Then from there, just press square to scroll down to the genres when you're at the radio screen. Press "Metal" and ChroniX Aggression should be first to play. =D
Just be careful, you may be fooled that a page ends somewhere it doesn't. Use scrolling frequently to see if a page really ends there. XD
Believe it or not, I found chronix on my PSP, becuase I was looking for music I liked on it, and heard saliva, seen the URL, and now I'm here. Lol, funny things tend to happen, eh? Love the station, thanks for it, and keep up the great work. I will donate when i actualyl get a job and bank account and such.
