BlackBerry is winding down its BBM Music service over the next two months, according to an email sent to current subscribers. April is the last month that subscribers will be billed, and songs will start becoming unavailable in May.
The final shutdown date is June 2, 2013. BlackBerry is promoting Rdio as an alternative, and offering a 30-day free trial of that service to affected subscribers. BBM Music was never brought to the newer BlackBerry 10 OS, and Rdio is not yet available for BlackBerry 10.
BBM Music was introduced just a year and a half ago. It was a social service that let users share playlists of songs. Each user could contribute up to 50 songs, and users with more contacts had access to more music. The service cost $4.99/month.
