In the western hemisphere Guitar Hero was the most popular game of this genre. Music tap games. You tap in rhythm of a song. If you think that's easy, think again.
And that's where it gets challenging. Yes, you can play some easy songs, but if you want to participate in international challenges, which you can with this app, you'll better train a few hours per day.
There will be insane levels when your finger need to fly over the screen like crazy. Lot's of different songs are ready for you, more challenging every time.
If you are into such games, this one will you bring many hours of fun... or frustration :)
