Hip Hop All Star is an app that that allows you to scratch and mix original songs. They have Green Lantern’s co-sign and tracks from Busta Rhymes, Kid Cudi, Kool G. Rap, Jason Nevins, Mya and Ray J to name a few. The game features real time scratching controls and touch screen to mix and win over the crowd. Head to head competition is also available. The app drops in September for iPhone and iPod Touch. This should be a good warm up for Scratch and DJ Hero. Hit the jump for the trailer and more pics. After the jump »
