yes it's fun and entertaining, and scratches the itch that guitar hero and rockband left behind. BUT, this app has some scummy practices. you miss a beat in the song you're playing and you either 1. PAY to continue or 2. have to restart. you shouldn't have to pay real money just to continue the song, but of course they did this because they knew they'd make money - otherwise it'd just count as a MISS and the song would continue like in guitar hero/rockband.
