Last iphone version you could not scroll though songs you had a simple dot on the song bar to rewind or fast forward.With iphone 3.0 update song scrolling is even more simpler all you have to do is to move your finger and you can scroll through songs at various speeds.

Whats more interesting is that when your drag drag your finger left or right you actually scroll through songs and if you do this movement while dragging your finger down the screen, the speed decreases to “half speed,” “quarter speed,” or “fine scrubbing.”
