I heard this song on Greys Anatomy tonight...?

[Michelle]

Please help!! I heard this really good song on Grey's Anataomy tonight, and i just can't stop thinking about it. It was during the scene when they were operating on the little boy with the ulcer in his stomach, and when 'Callie' and 'Mark' started kissing. It says 'cant replace and now we have', 'you took most of my life', and somewhere in there is says 'this was made for us'. It has kind of a techno-ish beat. Like I said, I really like it and would really appreciate it if you could tell me the song. I tried searching google and bing for the lyrics, but nothing came around!! D:> Pleaseeeeee Helllp!!!!!!!!!!!!!!!~? Thanks.
