Tetris and music

i'm currently back into playing long hours of tetris again. i don't know if its because i want to do something other than uni or if its because my high score was beaten. i think its mainly because i want to keep my mind off other things that can really upset me. To keep my mind away from sadness i've changed my music list to extreme rock, heavy metal, punk and gothic. It seems to be working so far. Some of these songs are really good. Some are also really crazy. i better start my uni work after i beat the high score.
