I do not own either of these song versions, they belong to both amazing artists. All I did was mixing Boron's rap with Glutamine's singing parts. Image also not mine, I put it together from two Zerochan sources. Download song: https://tinyurl.com/mozaikglutamineboron

Glutamine's version (YT):    • 【そんなふいんきで歌ってみた】モザイクロール【ぐるたみん】  

As a note, I know I'm no pro sound editor nor did I manage to get the absolute best sound quality. I tried to get a final result that sounded as clear as possible without too much difference between the parts from both versions, so please bear with me.
Also, I don't have romaji lyrics for the rapping parts. I'm not sure anybody has, but if you can find them I'll be extremely happy to post them here as much as follow them.

I hope you enjoy!
