The game in question had awesome pixel art of a city (at least the first stage) in the background...the game played like this-a multi track beat would play, and you had to lay out the beats on a grid, by lighting up boxes, before a scan line passed by, though I think you could pause the music, arrange the beats, and then hit play. The music was multi track, so on a given level you might be required to quickly arrange a beat with four instruments, and successfully completing levels would open up new instruments to use in the games' free-form beat creation mode, which allowed you to create your own loops and upload them to Facebook; as well as downloading other people's created loops and rating them. I had the number one ranked song, so I would really like to get this game again I purchased this game on a different acct. so I have no way of searching my previous purchases or trying to find it on my PC.
Just a keyword would be great, so I could search the appstore. I know Slide To Play had it listed, once upon a time, in one of their must buy lists. I think it might have been by a major publisher, but am unsure.
I am virtually certain that the game you're asking about is called Beat It!, published by Glu Games. This was released prior to Glu's shift away from paid apps to the current free-mium model. The app is no longer found on the AppStore, sadly. It still runs fine for me on the current iOS (note: Facebook/beat sharing capabilities no longer work), but I don't expect functionality to last forever without an update, which is highly unlikely; the imminent release of iOS6 may turn out to be its death knell. Still one of my favorites, and an unfortunate end to a really great app. I hope that helps, despite the disappointing availability issue!
Thanks a lot. It's a shame...since I used a different account, I can't access it. A great game made by Glu...those were the days.
