* Writing 312 solution wasn't that hard.
* "Smells Like Teen Spirit" is fun and easy to play on the piano. I just listened to the Bad Plus cover for a little bit and figured out it was Fm-Bb-Ab-Db the whole way through. Melody's pretty easy to get. Probably a capo on the first fret on the guitar?
* The annoying system beep that occurs in windows whenever I press too many keys can be disabled by going to the Device Manager, showing hidden devices, and futzing with the settings under Non-Plug-and-Play-Devices->Beep.
