Folks playing Bandori EN need to remember that when it comes to potential collaborations and covers, the chances of getting something BIG such as a popular anime, video game, or song that can easily reach the Top100 chart... are almost next to impossible since unlike JP, copyright is a thing and it costs A LOT of money to pay royalties!

It's wonderful that EN goes out of it's way to try and give it's players collabs and surveys unique only to their server, especially since it would've been A LOT easier on their part to just... not do that. That being said, it really is important to remember that money will always play a big part into why certain collaborations are never going to come to fruition. Even with how meme-y Baby Shark was, it made a lot of sense that that was picked in comparison to it's competition at the time (All-Star & Despacito, both of which would require a lot of royalties to be paid).

It's good to keep these things in mind when other surveys on EN eventually come out, to think of potentially easier (but also fun and enjoyable) collabs that might have a better chance at winning!

EDIT: also, unless stated otherwise, the chances of the actual seiyuu covering the winning collab songs (and getting costumes out of it)... not happening either since it's unrelated to the singers/artists at Bushiroad.
