Mainstream Radio 

Music that you love but gets fucked up by some retarded radio hipster DJ. Mostly music that has a genre that isn't too exposed, such as House, Dubstep, or Screamo.

Ghosts N Stuff was a great song before Mainstream Radio fucked it up.

Mainstream Media

A common form of worldwide brainwashing which influences weak-willed people across the globe and is committed to spreading propoganda and fake news. Whether they’re left-wing or right-wing, the rats in charge of these organizations are cowards who simply yearn to watch the world burn in order to make a quick buck.

Never trust them.

CNN: “I’M OFFENDED, HOW DARE YOU SPEAK YOUR OPINION.”

FOX NEWS: “IT’S NOT MAKING ME ENOUGH MONEY, SO IT HAS TO GO.”

Sane Individual: “Take all mainstream media gossip with a grain of salt and think for yourself. Always speak your mind (in an appropriate setting), and make a living doing what you love, —but remain humble and don’t be greedy.”
