I am not sure of that, but someone else will probably reply with help for that. I just wanted to mention I just had great success with "FlyCast" on my Bold. It streams the music to your blackberry as an application, not on a website. Another great one that I think is competing with the one I just mentioned (maybe?) is "SlackerRadio" which is what everyone here in the forums are going crazy over. I would've probably too, except it didn't have any Japanese stations available, and Flycast did.
