Google Play Music All Access (great name!) requires Flash in order to play any music. Unlike Spotify, they do not have a native Linux client. If you abhor Flash for security and performance reasons, GPMAA is much worse on Linux than Spotify. Rdio's HTML5 interface works perfectly without Flash. I recently switched from Spotify and I'm pretty happy so far.
