Teen spirit feature some variations of a music quiz game (it is inspired from my iPod) and the interface reminds "who wants the millionaire" tv game.

The general idea is to select as quickly as possible the correct track that you listen. The games feature a total available time, a bonus in a correct answer, and a penalty in a mistaken one. (example 30-3-0 means 30 sec total, 3 bonus, no penalty)
