Sorry for the long wait, I was waiting to see if Repentance + goes out of beta, but here it is.
Now [semi] compatible with Repentance +. Semi because for some reason all of the tracks work except for Downpour (The Reversed version works weirdly enough), I tried many ways to make it work, but maybe it's a problem on my end, let me know if the problem is still there. Also, did you know now repentance + merges the "resources-dlc3" into the whole "resources" folder? Now it's named "repentance" and it's in the same directory where the rebirth/afterbirth music files are located, and the layer for the blue womb rooms was moved to the "afterbirth" folder. Crazy right?

!By the way. I kept the "resources-dlc3" folder in the files for the people who don't want to upgrade to Repentance + just yet (I get you, it's still in beta).

Added "dogma appears" sfx to make the dogma fight introduction more consistent.

Added a track for the credits after obtaining Dead God

Swapped the song of boss rush with the one from ambush + new jingle.

some minor fixes

There were some songs that I also wanted to add, but couldn't decide between each one while making the mod, these are stored in the "Song Alts." folder (mods\The Binding of Synth\Bonus\Song Alts.).

-Fixed the transition between the dross song and it's heavy version

-Some songs have been changed because they didn't fit enough

Changes:

Boss Rush: King stephen - Monsters Aftrer Midnight /// Changed by /// Dance With the Dead - War

Gehenna: AINOMA - Manhunter /// changed by /// Tokyo Rose - Blood Oath
