1. A large stone

2. A type of music which has evolved in the last 10 years, this type of music contains depth and thought and most of all talent. Not just screaming and loud guitars with a drum beat in the background, as most people presume, yes it has instruments, which is obviously much better than some girl singing over a beat which replays over and over throughout the song. Rock music is creative, imaginative and unpredictable. Fuck pop and it's culture.
Not recommended for those who have bad taste in music.
