Music help!

What is the song with these lyrics: Where did you come from baby? Your eyes are like the sky. How did I find you? I can't believe you're mine.

Then you can't hear it because Karen and Sophie are talking. and it goes:

Now because you're mine, how can I try to keep it that way?

The episode is called Dark, Room, Chemicals. When I searched the lyrics I couldn't find anything.

And is there any site that I can find listings of the music they use?



Yeah, that's me, I'm fast...I'm the perfect storm of caffeine and genetics.
