Well. Searching every where known to understand how this "new" feature works. I got what it needs to play the song. But now I have a strage problem. (I'll try my best), it sounds out the game, when is pause, or in the main menu panel/settings/keyboard (anyway you call it).
The thing is, that maybe, and in the majority of that maybe, my computer is the trouble-maker. Bc is an XP hahaha... but this things never give you all the posible issues.
So I need your help. Thanks for taking care about my problem
