I was playing around on my gutiar and discoverd the chords to a song and idk what song it is and ive heard it before but i can only remember the beging gutiar part

It gos like:

Da da nu nu da da

It starts with a G power chord and then lift off the first finger and then back to the G power chord.

The answer is Paint it Black.
Be on the lookout for ghosts and the neighbor with the guns...oh and the mummified remains in the walls of your basemant.

no im almost positive its not a stones song...

All I can think of is AC/DC's "You Shook Me All Night Long" and Van Halen's "You Really Got Me".
