Albums like ARTPOP went to #1 across the world, albums like Britney Jean spawned at the least a moderate hit, albums like The Spirit Indestructible were made on a low budget with minimal promotion and should arguably be held to much lower regard, albums like Bionic were an artistic and experimental risk that saw the artist go completely outside the box and should at least be applauded for their courage and envelope-pushing.

Rebel Heart had the following:
- Major cross-continental promo and promotional performances across tons of major markets, including one of the biggest of all, The Grammys
- The accidental super-promo of falling over going viral capturing the world's attention
- Huge, trendy names like Avicii, Nicki Minaj, Diplo, Natalia Kills working on the record (all of which are proven and acclaimed industry names)
- High-budget video in Living for Love
- Ticket bundling

However:
- Album failed to go #1 in the US
- Living for Love failed to chart at all in spite of Grammys performance/video premiere in the same week
- Living for Love didn't hit the Top 20 in any major market and didn't chart at all in many larger market's charts
- The Rebel Heart tour sees Madonna downgrade from stadiums to arenas; arenas with tickets that are still available
- Rebel Heart is set to have one of the biggest 2nd week declines in Billboard 200 history

All things considered (promo, budget, name/brand/starpower), is this one of the biggest flops of all time?

theres no Born This Way anymore to help her

Yes, and considering the amount of promo aswel makes it even worse

Living For Love was such a horrific single choice

LFL, like the era itself, was hurt by the leak.
Ghost Town is already top 20 on AC.

Spirit Indestructible says hi

The album went #1in like 10 countries and even if it does not generate hits, it it will have one of the biggest tour of all time, yeah what a flop.

It was #1 selling album tho so not technically and #1 Worldwide album. Not biggest flop

So push up the release date like Marina did?

The music just isn't good anymore. Yes, this is the biggest flop of all, but people are going to use her age as an excuse and justify it by her past chartings.

Was there another song originally penned in to be the lead? I just refuse to believe that was executed as intended

Inb4 the leak excuse. Leaks have been proven to increase album sales, and only super hardcore stans even download leaks. I own every album by Madonna (except the movie soundtracks) and I couldn't even find any of the leaks.

The GP is not here for her desperate publicity stunts. She's not respected as an artist, she's more of a joke of what she used to be.

Unapologetic Bitch was the original lead single planned

monsters still so obsessed

I can't argue with those receipts, so yes.

it's commendable that as a 56 year old pop artist, she's still able to even debut at #2

then you factor in the fact that the album leaked 3 months in advance (although, to be fair, no one but stans really knew or cared and Madonna's team did a fantastic job of sweeping the Internet and getting rid of most of the leaks, I looked for myself and had trouble)

it's certainly an underperformance (so yes, a flop) but....... lol she's still Madonna and her career still runs circles around the rest of these girls. One huge flop isn't gonna change that.

It's a shame because the album is actually really rather good.

Waiting for Hilary Duff's release if it ever comes.

There's Avril Lavigne and Britney Jean. But okay.
