........ IN ORDER TO FULLY PUT YOUR IPAD TO SLEEP, PUSH AND HOLD THE POWER BUTTON FOR A FEW SECONDS. When you turn it back on, you'll notice that the music player on the iPod app is off, not just on pause.
It's called the Sleep/Wake button, and pressing it momentarily will lock, or sleep, the iPad. There's no need to hold for several seconds and, in fact, doing so will present the red PowerOff slider. If you slide it, you shut down the iPad; if you cancel instead, you stay locked.
If the iPod is playing, sleep or locking won't stop it; it just keeps playing, and continues to play when you wake up the iPad again. If it had been paused, it comes back still paused on that same track. There really is no "off" state for iPod, no Stop button, etc.
