Samsung p2 mp3 player problem THIS IS AN EMERGENCY?

My samsung p2 froze up when I was selecting a song to play and it won't do anything no matter what i do. i've tryd to plug it in to the computer and charger and nothing happens.I don't want to erase my songs i have on it or anything so should i wait for the battery to dead? my sandisk sansa e-250 froze up one time but i just took out the battery and put it back in and i can't do that with my samsung p2
