In the mean time, I found this:

http://code.google.com/p/tapsoffire/

Somebody mentioned it in this thread already, but I searched the market for it, but it didn't appear. It probably wasn't designed for the Nexus so it didn't show up, but there is a Droid version available from the Google code page. Free and open source!

One of the best music games is Taps of Fire. I have it installed, I recommend others to download this app too, only bad thing is having to hit the notes a little early, but its fine.
