( . . . )

I decided to make a playlist with the tboi floors and modded floors OSTs, credits goes to Ridiculon (Tboi  main game Ost), RenRen (Fiend folio Ost and Excelsior Ost), Wertandrew (The Revelations Ost)

The binding of isaac all floors Ost + Mods and more...

Caesarian (Utero) - The Binding of Isaac: Repentance OST (Album Mix)

TBOI OST - 21 - Perculum "Risks" (The Celler)

TBOI OST - 36 - Fundamentum "Foundation" (Burning Basement)

You may have noticed that I uploaded this song before but deleted it, the reason was just because the song wasn't as good of quality verses literally every song I have posted, so I fixed it.  Enjoy! :)

TBOI OST - 2 - Diptera Sonata "Song of Flies" (Basement)

The Binding of Isaac Excelsior OST: "Four-Days Dead" Corpse

The Binding of Isaac Excelsior OST: "Martyr's Tribunal" The Womb

The Binding of Isaac Excelsior OST: "Deanimus" Scarred Womb

artist of this OST: RENREN (also credits to him)
What is mortis? you may ask. 
Mortis is an unused floor which would have been an alternative version of the Corpse floor (or chapter 4.5)
But now this track plays in the Mortis modded floor from the Last Judgement mod
