Hey, I'm a long time fan/user of IPT/iPhone apps, and here are some I'd like to see: Improved Tap Tap Revolution: Just like 95% of people who use TTR, they treat it as a mobile Guitar Hero. I think the next TTR Should have the following features: A.5 Different Lines of Notes to hit from, like GH. Also it diversifies the gameplay. B. Downloadable/Customizable Themes. C. The Name, Skill, and Time Remaining of your Song on the HUD. iVisualize: A simple visualizer for music. iHear: An app similar to the iApp-A-Day's "Wallpaper" app. With WiFi, you can see what songs/movies other iPod Users have last listened to/watched. Socialize: Similar to the Youtube app. You can view MySpace, Facebook, Bebo, Friendster, and Orkut conveniently. GarageBand: You heard me. A portable version of the music-creation tool.
