Right then, unpopular opinions...
Pony related:
I like Sweet Apple Massacre.
Rainbow Factory is worse that Cupcakes.
Whilst Fluttershy is cute, I think she is overrated
I dislike most brony music.
Other stuff:
I prefer classical music to modern music, any form of it e.g pop or dubstep.
Windows XP over any other OS.
I dislike Call of Duty.
Begin the hate!
