Non-angsty? Jeez, that's tough ... George Michael/Aretha Franklin "I knew you were waiting for me"? I mean, the voices are male/female but I don't believe the lyrics specify....

Oh, and I have a disgusting fondness for "Here in your car" by hellogoodbye. It's very shaming.

Oh, oh, and this isn't gender neutral, but if the purpose of the request is what I think it is, it might work anyway - Weezer, Buddy Holly.

I'm shutting up now :-).
