Wow too many to pick...a few off the top of my head (and some mentioned above already I'm sure)
Janis Joplin
Pat Benetar
The sisters from Heart
Lee Aaron
.....I'm not aging myself here I hope.....
Cheryl Crow (that ballad with Kid Rock...well rocks)
Faith Hill (for one song only as I'm not into country per se)
