The purpose of this thread is to post a song that you think suits a member's personality in some way, a song that you believe they should use as their identifier. It doesn't have to be just one song. It could be several.
Remember, the song must relate to the forum member that you are posting it for in some way. Make sure you mention who you are posting the song for, and do try to cut down on the size of the song you post. After all, its more civilized if you can see the fucking screen, you know.
They can be from youtube or elsewhere, who cares.
