There are so many different ways to control music playback in iOS, such as through the music app, in-line remote control on iPod earphones, and by double-tapping the home button on the lock screen. With HomeScreenMusic, a free jailbreak tweak on the BigBoss repository in Cydia, you can also control your music by tapping an icon on the SpringBoard (otherwise known as the home screen). By tapping the icon, it will automatically play or pause your music. You can also hold down the icon to reveal back and forward playback controls. Pretty nifty, indeed.
