The last boss's theme in the Danmakufu Touhou game "The Last Comer", Iesua Nazarenus.
Earported by yours truly (yes I can't believe I managed to make it either), fits all the kinds of those long neverending annoying final levels where you have tons of gimmicks all the time and if you die you have to redo all of it. The song itself is very long and varied, so long levels are the way to go.
Note that it's slightly different from the Idol version (available on my Youtube), since I had to downsample the biggest samples (the organ, the bell and the strings+organ sample).
Also, not compatible with Yoshi's SFX. It uses the #noYoshi sample group, except that this time it's incorporated within the .txt. No need to add stuff in Addmusic_sample_groups.txt anymore!
EDIT: Added a version that is compatible with all global songs, but with less echo.
>tfw knew it was a 2hu port and a Wakana port from the very moment I heard this on Idol
>didn't know it was from a random 2hu fangame instead
maybe that's why I couldn't find the song then (also the fact that the only Touhou character that's the closest to being Jesus related is Byakuren, and she's nowhere near to being a loli, so RIP; I also thought it was Shikieiki's theme too at first lmao) >.>
about the port tho, tbh, I actually thought you used a MIDI of this due to how long the song is, but damn, you've actually managed to do a 4 minute long song in this way, I'm impressed
