REAL music? Isn't all music real?

Ever seen those things that say "Justin Bieber's music is CRAP! Listen to REAL music! Like A7X!"
I'm a fan of A7X, and Justin Bieber, guys.

Any string of notes that makes a melody is music. You might not like it, but just because you don't like it doesn't make it not real.

That would be like America saying "We don't like Afganistan, so it's not a REAL country. Loser country!" But we don't do that.

I found a comment on the music vidoe for Afterlife, saying "Just because You don't like it doens't mean we should have to read your f***ing comments. You knew you didn't like this song, so why leave a stupida** comment dissing them? SO F*** OFF!"

Went of over to listen to the song Baby, same guy left a hate comment on that video. Hypocrit much?"

This is a popular one.

"You say Lady Gaga, I say Nirvana.
You say Hannah Montana, I say Green Day.
You say Owl City, I say Linkin Park.
You say Jonas Brothers, I say Slipknot
You say Justin Bieber, I say Queen.
You say Taylor Swift, I say Guns & Roses"

Mine would be:

You say Justin Bieber, that's alright.
You say A7X, that's fine, too.
You diss someone because they like one of those, not cool.
