Don't watch it, it's not worth your 150+/- pesos, trust me. I watched it last Wednesday with my parents so I didn't have to pay for it with my allowance. Hahaha! It was so dragging and terrible. The only interesting thing about it was the gay tension between Edward and Jacob while Jacob was topless in a tent with Edward and Bella.
Neutron Star Collision was played during a graduation party at the Cullens' house. Bella was talking to some friends, then NSC came on and one friend exclaimed something like, "Oooh, let's dance! I love this song!" and then they went off to the floor to dance, then Bella walked away and bumped into Jacob (or was it Edward?), then they talked while the music played in the background.
