Music Dictator
One who believes that the music they are listening and playing is what everyone around them wants to hear, when in fact they are just being ignorant pompous assholes who think their taste in music is better than others, so when you try to listen to what you want to hear, the music dictator will turn his/her music up louder than yours, because the music dictator thinks your taste or song selection sucks.
Jim- "Every time I go to Sarah's house, her big fat brother always plays music, even when I am trying to sleep with her, her brother for some weird ass reason plays Marvin Gaye, he is such a Music Dictator!"
