The combination of looking up TMBG oddities and rarities and Bocchi the Rock content has managed to get the youtube algorithm to recommend me something with absolutely perfectly coalesced "dudes rock" energy. This guy who has this incomprehensibly regular upload schedule of translated songs into Japanese including several by TMBG.
Kiss Me, Son of God is the first one that I encountered:

but there's also Ana Ng:

and I found The Statue Got Me High way down there, but there's so much here I might have overlooked others:

EDIT TO ADD Puppet Head. Because I love Puppet Head, and so should everyone else

Bonus Yeh Yeh, which I include both because I quite enjoy the song and, hey, TMBG covered it too on Mink Car:

me, describing what's been coming out of my speakers for the past while: "i'm in awe. this guy, he's been so consistent about making these, for so long -- this channel goes back for years and years, there's nearly a thousand of these!"
her: "he's really the tom scott of japanese translation ukulele/kazoo covers of english language popular music"
(but then like. each of these only has double digit views, he's got like 500 subscribers and he's still kept at it for 6+ years. phenomenal dedication!!)
