My Top 10 (give or take)
1. Steve Perry (Journey)
2. Steven Tyler (Aerosmith)
3. Steve Winwood
4. Hmmmm, out of "Steves" now...so how about Paul McCartney. He has that rock & roll voice that always got me.
5. Lou Gramm (Foreigner)
6. Neil Young
7. Neil Finn (naturally--did you think I could leave him off??)

8. What's that guy's name from Nickleback? Chad Kroeger? (I think). Even if you're not a fan, he does have that cool r&r voice
I just noticed that all of my choices are men, so I'll add:
Melissa Etheridge
Pat Benatar
I also notice that all of my idols are from like, 20 years ago. Or more. ((sigh)) It's hell to grow old! ((grins))
