Serious Demo Glitch!

[CrocStock]

I know this isnt exactly priority as i havent bought the game (yet ) but i was playing the demo, it closed on me because the computer was just acting wierd, i decided to check the game integrity cache i think its called.  Well anyways everytime you do this the counter for the songs resets so you could play the demo for as long as you want.  I double checked this just to see if it was a coincidence and it isnt.
