I'm now trying my Nexus 7 2012 as an audio player for Napster and casting the audio to my Squeezebox Touch/LMS that is hooked up in my AV closet. I found a system-wide AirPlay caster for Android (AirAudio) that is working but seems a little flakey. My LMS box needs some maintenance so hopefully that will clear it up.

I decided to try using the native Napster app instead of a Squeezebox remote to control the LMS Napster app to make the experience a little simpler.
