Amanda Lear (obviously not because she's the best vocalist, but she had a major influence on my...well, what exactly?) 2. Grace Slick 3. Françoise Hardy 4. Nancy Sinatra 5. Grace Jones 6. Dusty Springfield 7. Annie Lennox 8. Debbie Harry 9. Carly Simon 10. Candi Staton 11. Toni Willé (lead singer of Pussycat) 12. Maureen McGovern (I find her voice so quintessential "American") 13. Mylène Farmer 14. Kate Bush 15. Alison Moyet I've typed my list really fast so I wouldn't start to overthink this.
