Teory music 53 - Version 1.2 Sound: 10. Sound quality is awesome!. I play the guitar, love to sing, and write my own songs. My teory on life.. well i have only lived 16 years so i would have to say that as you get older. I didnt see the video yet but it makes my teory even stronger. but I think the way the guitar sings in this is what seems to make this track so unique.
