Since the release of BBM Music we've not really heard a whole lot from RIM on how the uptake of the service has gone but they're still moving forward with promotions to get it out to a wider audience it seems. A new promotion for the service is happening right now for current Rogers customers where if you download BBM Music from February 1st up until March 30th, you'll get 6 months of the service for free.
A few caveats to keep in mind, the promo is for new and existing users but only if you're still under your trial term -- if you're beyond that, it won't work. Basically, you're just extending the trial. With that cleared up, if you've yet to try out BBM Music and are on Rogers, now is a great time to give it a go. Thanks, John!More information/download of BBM Music
