The Nine Lives of Chloe King Theme Song?

i've been searching everywhere, but can't find it! you know that little snippet of a song they play in the theme of the show, where it shows the bay bridge and it goes to Chloe landing on a roof and the camera zooms into her cat eye..? what is the song they play in that background? the lyrics are something like, "when worlds collide, i come alive..." but i cant find the name of the song or anything! does anyone know it!? thanks
