Sort through tabs and chords and pick whichever song you want to learn.
Lots of beginner stuff floating around in there. Are you trying to learn acoustic or electric? The songs will vary greatly.
I suggest learning a lot of chords and progressions before moving on to songs. It will help you greatly in the long run. It will seem very repetitive, but when you want to learn a song and there's quick chord changes, you'll be thankful you learned the chords.
Fuck, I'm drunk. Hopefully this was somewhat helpful.
