RIM has made a new build of BBM Music available in BlackBerry Beta Zone. The latest release brings the beta build to version 188.8.131.52. RIM didn't offer a change log, but we should be okay to assume it's just bug fixes from the last version they offered. We're also hearing that this may be the final beta before being pushed out to the masses in BlackBerry App World.
As stated in Beta Zone this beta test is only avilable to those in Canada, USA and the UK, so others will just have to wait as they continue the BBM Music rollout. If you arent already a Beta Zone member you can get in on the action at the link below.
