Good morning!

I have used this song successfully to wake up my teens for the last 3 mornings in a row.

Good Morning by Mandisa.

It's kind of hard to listen to this song and stay grumpy, so it's been good for me too.   The earlier they wake up, the fewer chores they have to do, so really, it's kind of tempting just to let them sleep all day :-P but I don't.  I wake them with this song during the 10 o'clock hour whenever I take a break from my work.
