I haven't had a music program that I have used this much. I downloaded Mobbler to help out a fellow member with a wifi bluetooth problem and cannot stop using it. Yes, it is a internet radio program but to me it is simply a Pandora radio in a different version. The speaker on my N95-3 is more than loud enough to just let it play when I am on Xbox, Sitting in my bedroom, etc... I have hooked it up to my Klipsch Ipod dock in the aux slot and it sounds great also. If your looking for a program that gives you unlimited potential for random music by a certain genre this is it or you save songs as your "Loved Tracks" and listen to just them later.
