Tap Tap revenge has become one of the most favorite free games on the App Store. The game has a high download record of 900 thousand and is expected to reach 1 million this week. This game will be the second application reaching 1 million mark after Facebook. Reaching one million mark will mean Tap Tap revenge is on 20% of all iPhones and iPods approximately.

Along with the game the company is providing free song download through the application. The songs for the game are submitted by Indie Artists and 2.5 millions songs have been downloaded according to this report.

Some companies are now eying to create song packages that match the beat of the game and deploy them as separate applications. Decrem claims that the company had talks with Indie and other popular artists to create package of songs. This takes us very close to the point where we will see applications meant for other application. It is fun to hear this type of new concepts.
