Brazilian readers have had access to Google's music store and cloud song storage for only a couple of months, but it looks like they now have access to the subscription music service as well. Brazil has been added to the list of countries with access to, uh, All Access, and at least one Google+ user has been given the promotional message on the Google Play Music Android app. Hop to it, music fans.

When Google announced YouTube Music Key, we had a few questions, most of which revolved around how this would affect Google Play Music All Access subscribers. Music Key's inclusion of All Access was part of the announcement, but it wasn't stated whether or not AA subscribers would automatically get access to Music Key, or if they'd have to sign up for the service all over again. Of course, that would be a really stupid way to handle things, so thankfully Google isn't doing that.

Update #1 (8/12/14): It looks like Google deleted the tweet embedded below. Between that and the lack of an update to this support page, someone might have pulled the trigger early. But if those countries don't have access yet, they probably will sometime soon.
Update #2 (8/19/14): After a false start last week, the Play Music expansion now seems to be live. The official Google Play country availability page has been updated to reflect this as well.

Perhaps you recall back in 2012 when Google caught some flack for its 10-device limit on Play Music access with only four deauthorizations per year. It was forced to backpedal and allow users to deauthorize unlimited devices, and all was well with the world. Well, until now. It looks like Google has started enforcing a limit of four deauthorizations per year once again. Support docs and the Play Music settings list the limit.
