If you've been against trying Google's Play Music All Access streaming service for lack of an official iOS app, it may soon be time to change your tune. Sources aware of Google's plans have let slip to Engadget that not only is the company currently testing a native Google Music iOS app internally, but that it'll launch later this month. We're told that while employees have been invited to test the app, Google still needs to fix a few bugs before it's ready for release.Google currently lets users in more than 19 countries sign up for its Standard and All Access music services, allowing offline and streaming access. Some users have made do with unofficial iOS apps in addition to a limited web app, but Google is said to be including the same custom radio and smart recommendation features found in the Android app. The company had previously closed the door on iOS users because Flash was needed to enforce DRM restrictions set by music labels. Now, Google appears to have overcome that issue and is nearly ready to launch.
