Nada Surf - If You Leave
It's a cover of OMD's version from the 80s (!) and I can't decide which one I like better. They have a different take on the song and I guess Nada's version sounds a little more sincere, like the quiet person who's probably not the most popular person around finally speaking up, asking you to stay.
The Quiet Person's voice is always more sincere.
Oh well I guess this is the start of Song of the Week!
