These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Accidental Innuendo: "Wow Wow VENUS", aka "Wow Wow PENIS". The album art doesn't help; it looks like Yoshitaka is staring at Sota's crotch.
Prim (the alias used for collaborations between L.E.D. and Mayumi Morignana) has proven to be quite polarizing amongst Western fans due to MM's squeaky high-pitched vocals.
DJ YOSHITAKA's songs are rather popular amongst Japanese players, but are ill-received by Westerners.
BEMANI in general has not been particularly popular outside of Asia, as current BEMANI games are all Japan-only arcade releases with ports on mobile platforms if you're lucky, and arcades are Deader Than Disco in the Western world.
Dance ManiaX 2nd Mix's DANGER screen. It's a skeleton on a red background that is reaching its arms out at you. Talk about an incentive to not fail...
"Survival Games -ZEUS Mix-"'s album art features Yoshitaka and Sota in a blue tint with creepy glowing blue eyes. The REFLEC BEAT plus version of the album art is even worse◊, showing Yoshitaka as a bald alien-like character.
