Any music that is not classical, rap, rock, pop, or indie.
That music isn't mainstream, but it's not really indie either. It's mainstream alternative.

Another way of saying "this person is mainstream", but its used to offend a person while still saying that they are mainstream.
Person 1:"Look at this Mainstream Fucker,I hate these Bastards"
Person 2:"Don´t be so harsh with him,he is not even doing anything provocative!"
Person 1:"I don´t give a shit!"

TL;DR Version:

Every news outlet is owned by a billionaire or $100+ billion corporation.

Every news outlet ignored or underplayed the Epstein story--not a single "journalist" (see: *company*) asked why the feds didn't try to strike a deal with Maxwell for the client list.

We know the client list. Bill Gates, Bill Clinton, and Alan "I kept My Underwear On" Dershowitz, Trump's attorney--none of them have been brought in for questioning.

***
(NOT TLDR Version)

Bloomberg is owned by billionaire Bloomberg. MSN is owned by Gates. Murdoch owns Fox News/Wall Street Journal. The Allbritton fam owns Politico. Carlos Slim has the largest stake in the NYTimes. Sumner Redstone owned ViacomCBS. Bezos owns The Washington Post...

Disney owns ABC. Vanguard/Blackrock are the largest stakeholders of MSNBC. Turner controls CNN, along with 200 countries around the world.

Other countries work similarly. The biggest publication in Belgium is owned by billionaire Van Thillio family... etc.

Meanwhile, every news outlet is sponsored by Pfizer ads--notice zero news outlets asked why "the science changed" so many times.

Why are you considered a "conspiracy theorist" and compared with flat-earthers if you ask these questions?

If you have good answers to any of these questions, then it sounds like the Legacy Media is for you :)

(Why did ABC and CBS (legacy media outlets) both censor the Epstein story and even fire a staffer for leaking the story?
"Little Libby Libby knew that white people were the biggest threat to humanity because she heard it from the TV--but what the Mainstream Media left out was that 5 corporations, all ran by a billionaire mafiia club, control all the news channels."

"Don't worry about the Epstein/Maxwell Client List; the Legacy Media *should* be talking about how Kanye West is mentally ill for wearing a t-shirt. And Tiger Woods having consensual sex with prostitutes receiving more attention than a cartel flying to an island for children? Pay no attention to the man behind the curtain."

"While you were out watching 'The Bachelorette,' the MSM convinced everyone that the biggest problem in the world was race... little did they know that the MSM was entirely and absolutely owned by just a few billionaires who needed to distract humanity from 'classism' because then people would REALLY tweak out."

Can mean a couple of things, including, but not limited to:

1. An indie musician or group who dropped their indie style and started making pop or rap.
2. A YouTuber who dropped their unique content and started making videos about Fortnite that are only entertaining to toddlers.
3. A politician who dropped their unique point of view for another one which is more popular.

In any case, there is a certain group of people that is left alienated, confused, and angry. Thus, this phrase.
1. I used to like Panic At The Disco before they went mainstream.
2. I used to like Lazarbeam before he went mainstream.
3. I used to like Andrew Scheer before he went mainstream.

A made-up but seemingly real phenomenon in where some tasteless, generic media or physical item (be it music, tv, literature etc.) which achieves way more attention and profits than which it deserves. It stays at the forefront of media attention from a mere 2 days (not so much a problem) all the way through several decades (major annoyance). This syndrome gets its' name from the fact that most modern mainstream media seems to hypnotise a large percentage of the population into becoming their slaves/army, often shooting way out of their target demographics. Over the past 5 decades, this syndrome has become more and more apparent, eventually leading to conflicting media/physical items and online wars that no-one cares about. Now, this power can either be used for bad, malicious, world controlling purposes such as Justin Bieber and Call of Duty or good, constructive development such as Minecraft and Gangnam Style.

It is currently unknown how people and corporations utilise this formula, but love/relationships are somehow involved in every single one. (Justin Bieber's songs, Avatar's romance, most Nick/Disney programs, a certain former little girl's cartoon that involves horses' current generation etc. Even small, obscure references to love such as Tetris' love heart in the high score screen can count. Another possible factor is that following its' popularity, metric fucktons of merchandise are produced, all the way from keychains to butt plugs.
1. Oh my god, did you see Justin Bieber last night? He totally hypnotised us with his bad voice and Canadian beaver teeth. I'll go buy 20 of his custom brand dildos for absolutely no reason!

2. The so-called Mainstream Hypnosis Syndrome is a lie! A dirty, filthy lie! We craft our products with heart and soul and totally no brainwashing, whatever that is, isn't that right Mr. errr, Snrub?

3. Out now! New Twilight sanitary pads! Feed Edward Cullen's current blood addiction whilst you scream in agonising pain after failing to make it to the toilet in time. Buy ASAP! Call 1-800-GOFUCKYOURSELF to order!

The legendary childish battle of Mainstream and Underground has been rooted itself into the modern world of western pop culture for as long as it has been around.

The two opposing sides, Mainstream and Underground, battle a hidden age long war between each other, some completely unaware of this raging war. Anything an Undergrounder considers to be corporate, or money making becomes Mainstream, and anything a Mainstreamer believes to be odd or extreme becomes Underground.

Originally based loosely on modern contemporary music such as Mainstream Pop vs Underground Alternative etc, it has now spread to anything controversial that appeals towards teenagers and people under the age of 20.

While most Mainstreamers are often clueless of what is actually going around them, and therefore being harmless, many Undergrounders (but not all) are well aware of their own alliance, and because of this, they often abuse situations where a Mainstreamer is seen in an Underground congregation.
A group of Undergrounders are seen at a party house at the beach and three mainstreamers walk by.
Undergrounder Jesse: OMG, OI SHIT HEAD, I EAT JESSICA SIMPSON FOR BREAKFAST YOU FAGGOT!!!
Undergrounder Billy: NICE ONE! NEXT TIME STAB HIM WITH YOUR PIERCINGS!
Undergrounder group: Turn up this slipknot shit!
Mainstreamer Sarah: Wow, um, what was their problem? I knew my new Billabong pink mini skirt would attract attention.. but this is absurd.
Mainstreamer Kelly: Like, totally! It's like we're in the middle of a fucking war!

Undergrounder Matt: Man, Maynard is totally selling out! He used to be cool, but now everyone's listening to three libras!

Mainstreamer Joey: What's new on the chart? By the way, I think I'll wear this pink flanelette to go with my lucky matching faded jeans tonight.
Mainstreamer Sam: Speaking of faded stuff, my skateshoes are naturally fading, time to get some new factory faded ones.

Pretty much the opposite of Mainstream music. Rarely, if ever, gets on the radio or top 40, and it's not usually well known to the general public. Also known as "Underground Music".
Non-mainstream music includes bands/artists such as Dream Theater, Porcupine Tree, Dälek, etc.
