It's almost way off topic, but if you like the rhythm games like that, there's a game called Hit Machine on the website omgpop.com . It's pretty cool, and you can play a bunch of different songs, ^^,
and it's free!
You just use the keys
and you hit the buttons as the bars pass the bottom, like guitar hero, but you DO NOT have to hold down on the long notes, it makes it easier not to, also, ya know?
