SHERlocked discussion

Ok, so how this works is you say a couple of sentences from a song, and then others try to guess the song. Try and keep it a song that most people will know, eg one that's been in the charts. I'll start.

It's too cold outside
For angels to fly

A Team, Ed Sheeran.

I have a heart, I swear I do
But just not, baby, when it comes to you

Ke$ha, Cannibal.

You say that I'm messing with your head
All coz I was making out with your friend

Avril Lavigne, What the Hell

You gave it up last week,
Now I’ve been losing sleep,
