Well so far I've listened to all these while drawing Optimus Prime:
1) Bad Romance - Lady GaGa
2) Black Flag Literal - Tobuscus
3) Me and My Broken Heart - Rixton
4) Pirates of the Caribbean - Theme
5) Arrival to Earth - Steve Jablonsky
6) Neon Lights - Demi Lovato
Yep, Pandora is pretty...random?
I'll be posting the finished art on DA, it looks like a freakin' photo!
(black and white, of course)
