Screen grab from BBM Music promo video.
BlackBerry maker Research in Motion says its music-sharing application for its popular messaging service is available for downloading in Canada, and in the U.S. and Australia within a day.
BBM Music allows BlackBerry users to select 50 songs from a catalogue of millions of tracks for their personal playlists. BBM users can share those songs from that list with friends who use the instant messaging service, meaning the size of the music library for listeners is limited only by the tastes of their BBM contacts.
More regions will be launched shortly. Users can swap up to 25 songs per month.
RIM unveiled the service in August and has been testing it since.
