BBM Music allows BlackBerry users to select 50 songs from a catalog of millions of tracks for their personal playlists. BBM users can share songs from that list with friends who use the instant messaging service. 

Research in Motion Ltd. said on its blog that BBM Music is a social music service that will be available for downloading within 24 hours. More regions will be launched shortly. 

RIM unveiled the service in August and has been testing it since.
