* Before Naoki Maeda composed music for ''VideoGame/DanceDanceRevolution'', he went by another identity, "Ensoniq Maeda", and composed music for other Konami games, such as ''[[VideoGame/{{Gradius}} Salamander 2]]''.
* Some of the BEMANI musicians play their own games, with varying degrees of success. ''REFLEC BEAT'' sound director DJ YOSHITAKA has [[https://www.youtube.com/watch?v=Y1ANh5bzCfQ shown himself to be able to play his own game very well]], and DJ TOTTO is a Kaiden[[note]]highest ''[[KyuAndDanRanks dan]]'' rank[[/note]]-level ''beatmania IIDX'' player. Meanwhile, ''pop'n music'' sound director wac is somewhat notorious for his appearance at JAEPO 2013, where he shows that his ''pop'n'' abilities...have a lot of room for improvement. (To be fair, he ''did'' play Ongaku [EX], one of the hardest charts in the entire ''pop'n'' series.)
* BadExportForYou: Arcade BEMANI games are released not only in Japan, but also other Asian regions, such as South Korea, Taiwan, and Southeast Asia. Unfortunately, only the Korean versions are translated; players in other non-Japanese [=eAMUSEMENT=] regions don't get translated versions.
* FanNickname
** 185 BPM is known by some as the "Yoshitaka constant" or variants thereof, due to DJ YOSHITAKA's strong tendency to use this speed in a large number of his songs.
*** In fact, it's such a prominent constant in his songs that [[spoiler: people initially thought that Rche was DJ YOSHITAKA's alias simply because of the use of repetitive chords and its bpm.]]
** "Soflan", a term used for sudden and dramatic BPM changes. The term originates from "SOFT LANDING ON THE BODY" from ''{{beatmania}} IIDX 2nd Style'', which shuffles between 79, 159, and 318 BPM. Bonus points if the song itself does not actually change BPM but the scroll BPM does.
* FanworkBan: From 2011 to 2015, the online service ''Programmed World'' allowed players on current BEMANI cabinets in [[NoExportForYou countries not served by the eAMUSEMENT network]] to enjoy functions and features that are otherwise exclusive to [=eA=]-connected machines. Unfortunately, in March 2015, Konami sent a cease-and-desist order to arcades running PW-connected cabinets as well as the PW staff, forcing the service to go offline. It is speculated that Konami is planning to expand [=eAMUSEMENT=] service to outside of Eastern and Southeast Asia, as on the same weekend, the [=eAMUSEMENT=] website [[https://twitter.com/polyphonicroom/status/574415118366175232 announced plans to provide global website service to players outside of Japan]], although whether this will actually lead to global [=eAMUSEMENT=] service has yet to be seen. (Hint: it won't.)
* NoExportForYou: If you were to make a pie chart of the number of BEMANI games released in Eastern and Southeast Asia and the number of BEMANI games released overseas, the result would be Pac-Man with a nearly-closed mouth. It got worse in 2012 when Konami started requiring BEMANI games to be connected to the [=eAMUSEMENT=] network, as well as making their games lease-only as part of the [=eAMUSEMENT=] Participation program rather than outright purchasable. There are efforts to run a third-party clone of the [=eAMUSEMENT=] network, but see FanworkBan above for what this can lead to.
