now have no idea how proceed.could please me out??by selecting song can played on device??

gamekit meant inter-device games. this, you'd want @ cbperipheralmanager or cbcentralmanager depending on device you're interacting with. it's lower level, you'll have more work set connection, there's tons of tutorials , sample code out.
