Who's the Artist???

This is something I did not mention in my first blog.  Who's that Artist is a game when I'll say a song and you have to guess the music artist that matches the song.  PLEASE do NOT comment the answers, I don't want you to give anything away to anyone.  So here are 15 songs that don't say the artist that wrote them.

1. Fireflies

2. Boom Boom Pow

3. Mony Mony

4. You Spin me Right Around (like a record)

5. Revolution

6. No Sleep til Brooklyn

7. Peace of Mind

8. Bad

9. Livin' on a Prayer

10. Vacation

11. The Final Countdown

12. Billie Jean

13. Meant to Live

14. Tonight Tonight

15. My Generation


I'll post the answers in a few days!
