Last night, I tried to master Rock Band 3's Bohemian Rhapsody on Expert Pro Keyboard.

It's pretty damn hard for someone who has never played piano before. I got to the point where I can play it at 70% speed and not horribly fail.

I just bought they keyboard and have only tried the songs I know, which there are very few of. I'll probably take a break and learn some easier songs first before coming back to it.
