Oh, you are good! I wanted to be first in with The Pretenders one, because I love Chrissie Hynde, and that song was my first slow dance. In Big Sur, CA. I date myself, but I was really young. Original: Melanie. I think #8 is Heart's "Magic Man." (Isn't that Heart? I didn't even google it.) I also got #1, 5 and 7, but I don't know the title, either. Who else sings in that accent? :whistle:
EDIT: I got #9: Robert Palmer, "Not a Second Time." That was hard, because the song is familiar, and sounds like the Beatles (which it is,) but an obscure track. And the voice is familiar, but you can't place it, if you're thinking 60s.
