It's an awesome way to get to meet new people from all over the world. All of the couchsurfers I met were really nice people.

Music As for music, I am falling squarely into the stereotypical computer scientist role somewhere between Epic Metal and Power Metal. (But there is some nice other stuff out there as well ;) ) Books I read mostly Fantasy - Terry Pratchett (most of them), Game of Thrones and a little Stephen King.
