Best Rock Song Ever!

Allman Brothers Band - You Don’t Love Me from Live at the Fillmore.   I saw it live at the Syria Mosque in Pittsburgh, Duane Allman killed it.  Listen about 6 minutes in on the album.  His solo was so soulful it almost moved me to tears.

Aerosmith ' Walk this way'
Bunch of zepplin
No Beatles please

Let me make a special mention. I was a boy in the 80's and I was dancing to Van Halen's JUMP with my mom. That song is still one of my favorites. The music video is great too. 

Thought of a good one...
Roll with Me - Johnny Winter And Live

Tough selection...impossible, but oldhvymec........you da man....and I'm not worthy!
