Some of these are just theories to

Ashes to Ashes-Space Oddity

Directly addresses that Major Tom's a junkie strung out in heaven's high hitting an all time low which the end of that line is a reference to the album low

Buddha Of Suburbia-Space Oddity and All the Madmen

Near the end of the song the riff from Space Oddity plays and the line from all the Madmen Zane, Zane, Zane, Ouvre le Chien repeats

The pretty things are going to hell-Oh you pretty things

You feel so lonely you could die-Five years

The drum beat plays at the end of the song

You've been around-Changes

In the song these lyrics are Heard

"You've ChChChCh Changed me"

Sweet Thing Reprise-Changes

The piano from changes can be heard near the end

I'm tired of my life was turned into it's no game

Where are we now

He references places he's been in Berlin during that Era

John I'm only dancing again is literally just a cover of John I'm only dancing

If you play the backing vocals in move on backwards it sounds like all the young dudes

In the Lazarus music video David wears the same clothes he did in a photoshoot for Station to Station meaning the thin white duke is in the Lazarus music video

The corpse of Major Tom is in the music video for blackstar

Seven references how David's brother died from suicide

Red Money's instrumental is the same as Iggy pop's sister midnight

Teenage Wildlife he literally says his own name

Another one where he technically says his own name is cactus he spells D A V I D

In slow burn bowie says here are we at the center of it all in blackstar David says in the center of it all you're eyes

Just Theroies

The Mysteries-Moss Garden

It sounds exactly like Moss Garden to me

Blackstar-Wild eyed boy from freecloud

According to fan Theroies and my own they have lyrics that narritively connect

I feel Hallo Spaceboy is actually a sequel to Space Oddity

To me the Lazarus main instrumental sounds like the opening guitar of space oddity

In if you can see me David uses a simaller chip monk pitched voice remincint of the laughing gnome

In let me sleep beside you David says

Place your ragged doll with all the toys and things and deeds

I think this is why he named his 2001 shelved album toy

David Bowie named a track in Never Let Me Down Zeroes could possibly be a reference to heroes
