Digital Trends – Details on RIMâs BlackBerry music app leaked out today from CrackBerry. According to their report, the music service is priced at $5 a month. However, BlackBerry owners will be able to activate a free trial of the application after downloading the BlackBerry music app. After activation, the user can download up to 50 songs at a time onto the phone. While the amount is extremely minuscule compared to Spotifyâs offline caching of up to 3,333 tracks per mobile device, users will be able to listen to the song library of anyone using the app on the contact list. The amount of allowed connections is currently unknown at this time, but potentially offers access to thousands of songs for users with many connections.Â
