copy all your songs from .sounds folder to any folder which you have created. e.g My Music folder etc. and make sure there is no .nomedia file in it. mine is overclocked at 1150 mhz. most of the time phone is running at 250 mhz. only sometimes especially when you play some hd games or use some really heavy apps then ur phone's processor will reach at 1150 for few seconds. its totally safe i guess to overclock.
