Thank you, I knew I had heard it before! It is from the walking dead. This plays when Rick meets the bicycle girl zombie. The full think is about 54 seconds.
Michael Gray - "The Weekend". Also known as "that song from tane.us". That part of this video also parodies the music video for the song, which is a very good watch, I might add.
Hah your a better man then me I guess, could you tell what song you used at 0:23? It sounds familar and I really want the full version in my favorites. Thanks! :)
