Google has updated its Play Music app with new options to control the quality of music playback over wireless networks and choose the compression level of downloaded tracks.
Previously, users of the streaming service could only adjust the quality of music when listening over their mobile connection, but the additional options offer the same control over WiFi and when listening offline.
The options to adjust streaming and download quality are listed simply as Low, Normal, and High, so it's unclear exactly what bitrate Google is referring to, but it's safe to say any increase in quality will eat further into any data caps, or use more storage in the case of downloaded tracks.
For comparison, Spotify offers a streaming choice of 96kbps, 160kbps, or 320kbps, while Tidal offers 96kbps, 320kbps, and Apple Lossless (Hi-Fi). Apple Music streams at 256kbps by default, but does include a 80kbps option for cellular connections.
