There was a song a long ago at MTV , that started be lighting the room. The gril walks in, and there are some men tied. One man is a contrabass player, one was a synthesizer( if I remember right) the girl was kind of torturing the guys and I rememer the scene where one tied man was looking the water bottle, as he was really thirsty, so the girl poured all the water on him.
I really hope someone knows this song, I have looking for this really long.
Btw, sorry for the bad english(not a native speaker)

The description reminds me of Playing God by Paramore. Did the girl have pink hair?
