1. Create an account on www.yourmuze.fm

2. Search for your favorite radio stations and add to your account. (So far I have found Hits FM, BBC Nepali Radio.... Kantipur FM link only takes me to a prerecorded show - at least thats what it was like the last time I checked... and I just added Gorkha FM 93)

3. log in with your account name and password at m.yourmuze.fm on your BlackBerry browser and choose any of the station that you have added on your account. 

No apps needed. The radio streams right from your default browser (using the default media player). 

I hope it helps.
