Of all the Castle and Beckett “walk out the door together” songs, this is definitely on our favorites. Here’s the catchy tune from “Law & Murder.

Artist:  The Daylights
Song: “I Hope This Gets to You”
Buy it on iTunes

You heard it when: Castle and Beckett, two nerds in a pod, headed to the Angelika to catch a screening of Forbidden Planet. Castle is a huge fan, but feigned ignorance when Beckett mentioned her love for the film so she would invite him along.  

This song worked because: seeing a movie together is a pretty big step. It’s dark in there. These lyrics adequately sum it up:

You’re like pretty Grace Kelly in a black and white scene,
And you’re batting your eyes cause you know it kills me
You think you feel my heart jumping through my chest?
When you look at me it beats three times as fast,
And all of this is passing us too quick for regrets.
And I hope, this
I hope this gets to you.
