After the trial period, BBM Music will run you $5 month. That fee gets you 50 songs to add to your collection. In addition to your collection you also have access to your contact’s collections as well. Obviously, this makes the experience with the app largely dependent on your contacts and the compatibility between their tastes in music and yours. $5 a month might be a hard sell for only 50 songs that you’re guaranteed to like, but with a four-month free trial on the table, it can’t hurt to try it out. Be warned, however, RIM will be requesting a payment method in advanced, so be sure to set a reminder in your calendar to cancel in case your not satisfied.
