I play the guitar. There's really not much of a difference between the acoustic or electric guitar -- so I don't know why some people are saying "I play the electric guitar." The main difference I've noticed is that, at least most, acoustic guitars only allow access to about the 14th or 15th fret, and the rest of the frets are blocked by the giant body of the guitar. Some electro-acoustic guitars have a cut away like the "normal" electric guitar, but doesn't give you much more frets. I personally like the higher frets on the guitar, makes a nicer sound IMO.
I can play the following pieces of various songs:
Buckethead
Soothsayer - Intro
Soothsayer - Main riff (I think it's the main riff anyways)
Soothsayer - Part of "Solo A"
Nottingham Lace - Main theme
Nottingham Lace - A slower solo in the song
King James - Intro
Somewhere Over the Slaughterhouse - Two random measures in the song
Final Wars - Intro
Final Wars - Large portion of the melody
Big Sur Moon - Intro
Halloween (Movie Theme Song) - Entire Song

This is Halloween (From a nightmare before christmas) - Most of the song
Pure Imagination - First few notes, lol
And some more
Misc.
DragonForce
Through the Fire and Flames - Intro (Just a TINY bit slower than they actually play)
Through the Fire and Flames - VERY small part of the solo
Ozzy
Crazy Train - Intro
Carlos Santana
Black Magic Women - Most of the intro -- I can't play the rest because I need a new high E-string.
As you can tell, I rarely get interested in learning a whole song -- gets too boring after a while.
