Performous

Everybody loves music and while one might be too shy to dance or sing, there is always some part for everyone. Performous is about improving your skills and having fun at the same time. No special hardware required, you may play guitar on your PC keyboard, sing on your laptop microphone and so on. If you do have SingStar microphones, Guitar Hero or Rock Band instruments, or dance pads, just plug them into your USB ports and start rocking!

Performous is free software and once you click that download button, you will find out that open source doesn't need to suck. In fact, many users keep praising us about how we beat even those commercial games.
