I think each remix should have it's own category on time completion, where Remix 1 starts as you press "YES" to choose your slot name, and would end as soon as you get your verdict. This would mean the next Remix, in this case, Remix 2 would start as soon as you get your verdict for Remix 1. (so as soon as you see "OK" or "Superb").

Since each stage is in a fixed time, I don't think having each remix as a category would be ideal. I believe there is enough categories for runners to get into for this game. I also want to maintain uniformity with the rest of the Rhythm Heaven Series.
