Hi, I just put together a litte wrapper app for Google Music on the Touchpad.
It is a very simple app to use Google Music on the Touchpad. It is basically only an Enyo webView that displays play.google.com/music. You can also do that in the browser of course, but the app has 2 main advantages: It supports exhibition mode and it keeps the screen on, when the app is open!
I'll try to put it on Preware but for now you can get it here.
For this first version: Make sure to stop the song before exiting exhibition. Otherwise it will play till its end or you'll have to start exhibition again to stop the song.

UPDATE: Someone asked for the source, cause he wanted to build another "viewer" like that. You can find it on Github.
