What video are you referring to? This post is just taking me back to this same page, I'm not seeing any video link. Maybe I'm missing something.
Getting Steve Jobs personal acknowledgement must have been pretty amazing. That's a good sign you paid attention to detail. I do think I can recall the visual customization done for specific artists and tracks, was very cool. Style matters alot for the vibe in music games, the attention to it is one of the reasons I always preferred Rock Band to Guitar Hero.
Thanks for the cool game! I was actually at uni for game development at the time and as one of my major projects I made a design document for a DJ music game. The Tap Tap Revenge series was definitely an inspiration and contributor to my love of music games at the time and I had alot of fun playing it. May have been one of the first few apps I ever spent money on.
It's making me nostalgic for the time when my smartphone was a new, cool, and fun device and not the addictive attention span sucking portal to hell it is now.
