It wouldn't be easy to look for Tap Tap Revenge on the computer, plus, you might even have to pay for it on the computer. It should be much easier if you get it on the phone. It's available any where except Android. The only version of Tap Tap Revenge for free is Tap Tap Revenge 4. You can still buy the others, Tap Tap Revenge 3 is the best because you can easily hack on it but you can't on Tap Tap Revenge 4. But Tap Tap Revenge 4 is the most popular version now because its for free. If you have an Iphone you might be able to get Tap Tap Revenge from your computer to your phone. It depends, like I have a Samsung Galaxy and I just get my apps from the Market (Android). You can still try and get it with other phones but an Iphone will be easier.
Tap Tap Revenge 4 is better for many reasons. It's much more faster and has better graphics and a better memory. There are also less glitches and it's online is much better.This is an opinion based answer and my answer is Yes.
Yes to purchase songs but you can still play the songs you already have on the app. However, your level cannot be updated with no wi-fi until you play another song after you connect to the internet again.
You buy clothes and accessories for your avatar :)
