Ugh I really don't know how it goes but I hear it at work every time since they have a playlist running.
The only line that I know is (I think) "You tell each other secrets", it's super slow, sung by a dude and IMO lame as hell. Some sappy piano music in the BG as well.
If someone knows what I'm on about, tell me because I'd like to bitch about that song to my friends.
