Constructive Criticism

Hey, I've got a few songs I'm working on that I wanted to get some feedback on.
I put them up at purevolume.com/tmbf
Right now its just the guitar. I just wanted you guys thought of the direction I'm traveling with them. (The second and 3rd song are suppose to just flow together back to back to compliment the lyrics I wrote for them.
Also, theres a link there to a song I put on youtube that I'm convinced I heard before that I played... Its pretty sketchy, but maybe you could tell me what song it is... if you heard it.
Thanks.
