Love is a Battlefield by Pat Benatar (playlist) is one of my favorite songs of all-times. Although several of Pat's songs would fit in that title. Power and passion pulsated from her rock and roll and flows into her covers.
For something differenct, I'll start off with a version by Pat Benatar & Neil Giraldo but not the original but a very nice slightly different acoustic version
Metal version with the Fires Embrace
Chris Norman (playlist)
Rather heavy metal version by Amity Affliction
Steve Lawson and Lobelia... although it gets weird after the during the guitar solo
Cheryl Hawrylko not really sure what I see n this one, maybe its the smile
For something special ... here is a really great Literal Video Version
