16. Yeah, the tune is much easier than the group. It's by the group Soft Cell, an 80s one-hit wonder AFAIK. (I believe I have it on one of the "Just Can't Get Enough" new wave collections.) I can see why you see similarities, but Sweet Dreams is by the much more significant Eurythmics (one of my favorite groups).

17. Interesting -- hadn't realized it was on there. But it's not the version in question...
