itunes playback?

Im having some trouble with my itunes. Wheni listen to a song say for about halfway through and then I change to another song and continue listening the next time i go back to the original song it start when i ended it. Lik eit is saving when i stopped listening to the song and it does this for all of them. Is there a way i can change this so if i change a song 1/2 way through the next time i go back to it, it will start from the beginning
