Yazoo - "Only You"
Only one other person in this thread has mentioned this song (back in 2008), and I'm surprised it hasn't been mentioned more, because I remember how popular the song was in the '80s, when it struck me as soon as I heard it because the mood of the song was so sweetly plaintive.
I actually think I remember the first time I heard the song: I was standing alone in a dark room with a radio on a windowsill at night, when the song came on. I stood still to listen to it and admire the mood it created.
I thought it was sung by a man! I didn't realize until recently that the singer is a woman with a rich, low voice.
