When i was a smack addict in the mid 90's i used to earn my money singing/playing guitar at a train station, i only knew one song and played it for 4-6 hours a day at the same spot. It was american life in the summertime and now everytime i hear it (which isn't frequently thank god) i breaking into a tears and begin to sweat a lot. A little insight, thats all, Its all about learning, you know.
