バッド・ダンス・ホール (Bad Dance Hall) is an original vocal track by the duo ぱなまん (Panaman, vocals) and カラスヤサボウ (Karasuyasabou, composition/arrangement/lyrics). It first appeared on the album カンパニュラ (Campanula) released in 2016, a year before its arcade debut. The song delivers an energetic, dance-oriented sound that blends J-pop and rock elements with a driving 152 BPM beat, matching its lyrics about breaking free from a dead-end, theatrical world and diving headfirst into a chaotic dance hall. A music video for the track was produced by Not-116 and 田中寛崇. In maimai, バッド・ダンス・ホール was added to MURASAKi PLUS on July 25, 2017, as a Standard chart set. Over subsequent version updates, its difficulty levels were adjusted multiple times, the Expert chart climbed from 9+ to 11+, and the Master chart rose from 11+ to 13, reflecting the community's evolving skill ceiling. Nearly nine years later, on April 3, 2026, the song received a set of DX charts via maimai でらっくす CiRCLE PLUS, unlockable through Friend Matching Season 27. The DX Master chart, designed by はっぴー, stands at level 13+ (13.7) with 881 total notes, featuring dense Slide and Break patterns characteristic of the designer's style. The Standard Master chart, designed by LabiLabi, sits at level 13 (13.4) with 797 notes. The song is also notable for having a separate Vocaloid version featuring Kagamine Rin and Kagamine Len, expanding its reach beyond the original human-voiced recording.
