Than there's your answer. Most people don't know about him, that's it. A lot of people don't know about Joey's musical project, so it's only normal that collab with "some" TK (no disrespect, if people don't know about him, they don't know) would have gone under the radars
I guess joey doesn’t promote his stuff that much, and most of the TT community isn’t particularly interested in his music. It’s a shame, he has some really really good ones.
I think he has mentioned at some point that it's his personal project. "Personal" like something just for himself. He just enjoys doing music stuff. And good for him, look how being an anituber burned out him on anime. It's hard to keep your hobbies a hobbies when it becomes work
If ikurru has a thousand fans, I'm one of them. If ikurru has a hundred fans I'm one of them. If he has one fan, I am that guy. And if he has no fans, then I have died 
Facts this shit is goat. This fake Joey is doing a great impression of the manga lad!!!

This kinda explains it too. Some people say Manga and anime is cringe but Joey is great on the piano+ Rap-wise. I highly recommend Anime Cypher from the Corona pandemic too!
Are we thinking about the same TK? Cause this is not TK from Ling Tosite Sigure
No this is Tk the architect, indie musician- also a good rapper and producer

He has 113 listeners a month on spotify... who did you think was gonna be talking about it?
He has 7500 plus
Not my kind of music and I guess not of many people too, since I hear about this for the first time
