RIM probably heard that one of the big things in tech right now is offering a music locker service because they just announced BBM Music. Too bad it's the worst music locker service in the world: you pay $US5 a month for 50 songs.
The $US5/month fee lets you keep 50 songs in your personal profile. Which, of course, is disgustingly little. And don't even think about swapping songs too much, you're only allowed to change up to 25 songs per month too.
Luckily, BBM Music has a neat-ish social aspect to it, you can also listen to the music that your BBM friends have loaded up to their library (which is mildly cool). They'll even let you build playlists with those songs! The idea is the more BBM friends you have, the more music you can access. Which sounds sort of fun in a vacuum but is a pretty tough sell IRL as everyone I know is ditching their old Blackberries for modern phones (and services) that can store 20,000 songs on the cloud.
