Today I was listening to my music on Itunes like usual..
then I decided to play some games eg ' war3,battlefield etc... ' '' RUNNING FULL SCREEN GAMES ''
After that my music got all laggy eg. music was running faster.
When i quit the game and put my music back on it was fine...

This is the first time I couldn't listen to music on itunes and play games..

Whats happening?

HELP ME PLZ!!!
