For music in PLII, try Diana Krall:Love Scenes. Tracks 2 and 11 are good. In track 2, listen to the difference in quality of the popping cork. Also, she should sound as if she's right there in your room. In track 11, listen for her to be front and centre with her bassist behind her.

For movies, Reservoir Dogs, Pulp Fiction or True Romance are good bets.
