v4.4.811H* Added ability to keep Thumbs Up, Last Added, and Free and Purchased playlists on device.* Auto-generated Instant Mixes on Recent tab based on your favorite songs.* Gapless playback support (on devices with Android 4.1 or later)* Improvements for keeping music on your device for offline playback.
I confirm that Google Play Music (Android's default music player) is now indeed gapless (at least on my Galaxy Nexus with Android 4.1.1, with Ogg Vorbis files):
Is that Vorbis files you loaded on the phone directly?
Last I knew, the cloud uploads are all stored as mp3 regardless of what you submit.
So is the only way to get gapless playback out of google music to have Vorbis files on my phone straight from the computer (i.e. not downloading from the cloud) and play them from my phone?
