I know some people on this website are aware of another website named last fm. On this site you basically keep track of all of the tracks and artists you have listened to through the days, months, years. I use this website and so does a friend of mine, where we do something we like to call artist racing. You basically listen to one artist repeatedly until you eventually surpass the other person and they give up or you become the #1 listener of that artist on the website. I had done this with a certain punk band a few months back, and I would listen to certain songs of theirs on repeat for up to 8 hours at a time. I'm not entirely sure if I went insane over that experience and didn't notice or if I was already so mentally deranged that it didn't effect me. Anyhow, I won that battle.
