What song is you? What embodies your temperament, your emotions, your personality? If you haven't found it yet, feel free to share a favourite song, from a video game or otherwise. And you're lazy, just go with Stickerbrush Symphony. It always shows up in response to this question.
Mine is And Yet It Moves by Fates Warning... The tempo shifts from high energy to contemplative and back fit me well, and the lyrics strike the same part of my brain that gets giddy when playing through nightmare worlds in Silent Hill. Plus the name of the song refers to Galileo's words before he recanted his scientific findings before the inquisition (it basically means, "no matter what anyone says, the facts will remain facts").
