What are songs about the music industry that you like?

Have a Cigar, Pink Floyd.

Life's Been Good to Me So Far, Joe Walsh.

Lito Shuffle, Boz Scags.

Jukebox Hero, Foreigner.

Piano Man, Billy Joel.

(Yes, I am old.)

Have a Cigar was the first song I thought of.
"Oh, by the way, which one's Pink?"
- I love that some music industry asshole actually asked them that once, and the quote made it into the song.
- Primus' rendition is also awesome. https://youtu.be/aEf0SpAEnIc?si=PVfnyKpxFRuslQXo
- A fun industry fact: Have A Cigar was sung by Roy Harper, as he happened to be in the studio and the members of Floyd thought he could be a good fit. Roy Harper is perhaps more known in the mainstream through the Zeppelin song Hats Off to (Roy) Harper than through his own recordings, though he's still alive and active.
  
  Harper didn't feel like he was appropriately compensated for his work on Have a Cigar, which is ironic considering the overall thematic.

They Might Be Giants - Rhythm Section Want Ad

They Might Be Giants - We're the Replacements

They Might Be Giants - the entirety of Venue Songs
- I almost included "The End of the Tour" but decided against.

EMI, Sex Pistols

Unlimited supply!

Interstellar555, the music video movie that accompanies Daft Punk's Discovery album

Don McLean - American Pie

Is it about the history of rock'n'roll, or something else?
- I have no idea WTF I just read. All I know is that I want to throw an onion at you now.

Dinosaurs will die - NOFX

Complete Control by The Clash

KoRn - Y'all Want a Single

Against Me - Unprotected Sex with Multiple Partners

Pop 101 by Marianas Trench. Very funny and also true.

I think Hank Williams III with the Grand Ole Opry Ain't so Grand deserves a shout-out. Basically a song about how the institution that chewed up and then expelled his grandfather can eat shit.

I think the most obvious album to point out which is about many things (including the abuse of the music industry) is To Pimp a Butterfly. I'm surprised I haven't seen it here yet. Even the title is very on-the-nose – the "pimp" in reference is both the music industry and (more frequently) the US government/social structures, and the "butterfly" is a fledgling Kendrick/black rappers/black Americans in general (context depending on the exact song). It's meant to be listened in exact order. Many people say it's overrated but I really disagree. It's an amazing narrative and powerful symbolism with good music.

lost in hollywood by system of acdown

I'd argue that Pink Floyd's Comfortably Numb belongs here: AFAIK it's about a band manager injecting the strung out musician with drugs, so he can get up and perform the show that night.

Maggie's Farm by Bob Dylan

Radio Friendly Unit Shifter by Nirvana

All the Best by R.E.M.

Intro by The Prodigy (not a song, technically, but a clear statement of intent from Liam Howlett)

Hmm songmeanings.com has following opinion about the nirvana song:

Kurt said it himself that this song has no meaning and that it's a bunch of random poetry lines thrown together to a kick ass motherfucking melody. This is one of my favorite Nirvana songs.
- Yeah, I'm going mainly by the ironic title to be honest - it always feels to me like Cobain's snarky response to studio pressure to make another Nevermind. I've not looked into closely though, I have to admit.

Cold - Kill the Music Industry

Spotify Link

Death on Two Legs - Queen

Porcupine Tree - The Sound of Muzak has one of my favorite lines ever in any song: “Music of rebellion makes you wanna rage, but it’s made by millionaires who are nearly twice your age.”

But glittering prizes and endless compromises shatter the illusion of integrity...

Comfort Eagle by Cake

Nice!

There's also this one: rock and roll lifestyle

To some extent, Sad songs and waltzes.

And I'll be honest I have no idea what this song is about, so who knows: wheels

So many songs by Muse which I find most amusing because they have an anti-corporate message but are made under a giant corporate label.

Specifically what comes to mind when it comes to the music industry itself are Showbiz and Uprising.

Cover of the rolling stone

Death on two legs, by Queen, is a track of reckoning with their former manager.

Plus it's a pretty little known but great early queen rock song. Freddie's viciousness really spews out from it.

Sweet Dreams Are Made Of This - Eurythmics

Show Business - A Tribe Called Quest

Welcome to the Machine by Pink Floyd is right up there.

Life's Been Good - Joe Walsh

Guns n Roses - Get in the Ring

Stone Temple Pilots - Adhesive

Barracuda by Heart

Mr. Recordman by Ugly Kid Joe

DJ Shadow Why Hip-Hop Sucks In '96

There's a good Russian song "The main problem of music in Russia" by Zakhar May
Too Long To Learn Russian: The main problem of music in Russia is that you're listening shit!

Drive By Truckers - Gravity's Gone

Elton John someone saved my life tonight song

Gillian Welch - Everything is Free

Oh and somewhat tangential but Hayes Carll I Got a Gig song - "playing for my dinner six nights a week, hurricanes, Easter, and New Years Eve, I got a gig baby!"

There's a song about how it feels when you get your royalty check. I think that's what it's about... Cannibal Corpse - Meat Hook Sodomy.

You can’t really get any more outrageous than Death to all but Metal

Good songwriters can do some good stuff when they are writing what they know. Bad singwriters can crawl up their own assholes, though. Some good Americana Alt-Country ones:

Mercury in Retrograde - Sturgill Simpson takes on the realities of "success". Really the whole Sound and Fury album, though; the whole thing is just him raging at the labels and expectations people put on him as "the next Waylon Jennings."

Bible on the Dash: Life for work-a-day touring musicians. Corb Lund and Hayes Carll actually come up with something useful about a hotel Bible.

Robert Earl Keen:

My Home Ain't in the Hall of Fame. Checking out of the Nashville rat race.

What I Really Mean: Wistful realities of road life for someone at a different life phase than the one above.

The Road Goes On & On: a vicious diss track at Toby Keith's expense. REK is like the chill Democrat New-Balance Suburban Dad of brilliant Americana singer-songwriters, so he probably wouldn't speak ill of the dead, but I will. Fuck Toby Keith.

Cracker - Ain't Gonna Suck Itself

Killpop by Slipknot, that song is amazing. It's very indirect, though, if I didn't read an interview that it's about the music industry, I wouldn't have guessed it.

Disorder and Disarray by Rancid. There are lots of great examples here, and I think this one fits.

Smile Empty Soul - The Hit

I can't seem to figure out how to edit my comment on kbin. I thought of one newer than Rush fom a band I've come to enjoy highly and hasn't been posted yet:

LCD Soundsystem - You Wanted A Hit

https://tomsmith.bandcamp.com/track/i-want-my-music-on-napster

Icon for hire - now you know

Specifically about the girls perspective

Jamey Johnson - Between Jennings and Jones

Well, some record executives found me one night I was singin' half-lit, they said it sounded just right (right) Put my name on an album but they shelved all my songs

Gillian Welsh - Everything is Free.

Great song about the difficulties of making a living off music now that everything is available for nothing. Father John Misty recorded a version when he was invited to the Spotify Sessions, which was a nice little fuck you to the people inviting him.
