morena y clara - "no llores mas" (download) (removed)
This one might not be for everyone, but I love it. Morena y Clara were a Spanish flamenco pop duo from the '70's. "No Llores Mas" (Cry No More) was much darker than their usual poppy stuff though. Sort of sinister Spanish synth if you will. Definitely not what you would expect after looking at the above cover. And the video could have been directed by David Lynch.
