First off, I'm intressed in who that might be intressed in doing this, and if you are, write here.

Thanks~

I am writing here.

hey,i want to participate

I want to make a part of 05 Kirby's Gourmet Race - Kirby Super Star BGM

I'll be interested.

If you get it off the ground.

I would love to take on a few parts!

I wanna be part of this

Meme wants in!! ;D

Interested.

here are the 4 parts i want( it is still based off 12 people with 4 parts each right? just recalling the conversation from earlier)

04 Caramelldansen - Song by Caramell
17 Melt - Vocaloid (Hatsune Miku) song by ryo / sm1715919
25 Dr. Wily Stage 1 - Mega Man 2 BGM
ED-6 Kirby's Gourmet Race - Kirby Super Star BGM
^^^if the ED one above isnt a song(just a bit confused) then replace it with the next one.
28 God Knows - The Melancholy of Haruhi Suzumiya insert
although im hoping that ED one i picked is a seperate song, but im not sure

and if for some god forsaken reason in the highly highly unlikely event of this not getting enough people i can take on more parts.

The "Ed" parts are just tiny 3~5 sec collabs of the longer parts in the song, so I tought maybe the person who had the respective part, could map the tiny part in the end. But yeah, let's see what we do about that.

23 U.N. Owen was Her? - Touhou Project BGM
24 Oyome ni Shinasai! - Touhou Project BGM (arranged by IOSYS)
ED-8 Kero ⑨ Destiny - Touhou Project BGM (arranged by Silver Forest)

46 Let's Go! Onmyouji - Shin Goketsuji Ichizoku: Bonno Kaiho insert

Yeah, just that

I'd like, "Ne Gi De Risetto," please. :3

EDIT: Or well, Ne-Ni-Ge de Reset! owo

Though, if I have to choose more I will, I guess.

I call:

12 I'm Lovin' It - McDonald's commercial jingle (Does that count?? XD)
18 Dango Daikazoku - Clannad ED
21 You Higurashi no Naku Koro ni Kai - Meakashi-hen game ED
36 Little Busters!- Little Busters OP
