6.1 works amazing on mac. A real Rock Band experience!
The best Singstar-like game.
Great SingStar-like game (it's just a part of its possibilities, and it runs with linux/mac/windows !). YES, we CAN ADD songs.
This is the best music game for linux due to its simplicity and performance. It works on windows too. I hope you keep the game simple instead of adding too many features.
Great game, it's a pity that it isn't that known.
