You should react to his Sung-Jin Woo song "Alone at Night", it's my personal favorite song from him.
I honestly was very iffy about it, but that ending solidified it for me. I've honestly liked Fabvl for a long time, and this just got me back into him. Also, BRING BACK GUMMIGOO!
Some Fabvl songs:
Nanami song The End
Vigilante Deku song Lost
Griffith song ft. Andreastormkaden hiding in the dark
Dabi song Cross my heart reimagined
Naruto song Under my skin
Record of Ragnarok Adam song Holy Ghost ft. AndreastormKaden
Gojo song Falling Down ft. Oricadia
Itachi song Nightmare
Kakashi song Alone ft. Dizzyeight
fun fact: he did this under 24 hours
