why does the MANIERA ffr page link to a clip from a japanese horse racing dvd

[Zapmeister]

here is the page for the ffr song MANIERA.

if you click on the artist link, where it says Musical Masterpiece, you get this gif

this is the same gif as this one that was posted to reddit r/gaming earlier today, except cropped. it was explained in the comments that it is not from a game, but a japanese animated dvd that parodies horse racing and stuff, called Japan World Cup.

i was wondering what the hell does the song MANIERA have to do with that. it's a fitting soundtrack for sure, but the videos in the reddit comments show that the dvd doesn't actually have a soundtrack, but only commentary.

a google search on maniera musical masterpiece shows up nothing

question: what the hell does MANIERA the song have to do with this japanese animated dvd?
