You'll never get anywhere playing songs from day 2. Trust me, I've been playing for over a decade. You'll always be playing in someone's shadow with no hope of being original.

Quit learning songs, do that if you want ass and impress the preteen chicks. If you want to play to really play learn chords, scales and how song structures form. Learn the 1,3,5 theory and the 2,4,6 theory. Or the 1,3,5 minor theory, etc.

Yes I sound like an asshole, but hey someone's gotta give you some proper guitar sense.
