As my followers on Twitter know, I know someone who listens to music through his headphones so loudly, that I can actually hear his music from several feet away. Now, some songs are just more distinctive than others, and one that I can always pick out, because of its guitar riff, is the Guns N' Roses classic, Sweet Child O' Mine. He listens to it at least once a day, and often times more than once a day. So here is the video for that song for your work week enjoyment.
And yes, he's listening to it right now as I type.
