迷える音色は恋の唄 (Mayoeru Neiro wa Koi no Uta) translates roughly to "A Wandering Melody Is a Love Song"; the game's ALL PERFECT称号 (title) officially renders the phrase in English as "A Wandering Melody of Love." The track is produced by からとP⍺ոchii少年, a unit whose name incorporates the Vocaloid-producer "P" suffix alongside the unusual Unicode characters ⍺ (APL functional symbol alpha) and ո (Armenian small letter Vo), and features vocalist はるの (Haruno). Released on January 10, 2025 as part of maimai DX PRiSM's launch wave, the song sits at 165 BPM in the Game & Variety category and is available across all regions (Japan, International, USA, China). The Master chart (Lv. 13+, 13.7), designed by はっぴー (Happy), contains 833 notes with a notably sparse Touch note count, only 10 Touch notes among 667 Taps and 88 Slides. This distribution is unusual for a DX-exclusive chart at this level, as Touch notes typically feature more prominently to utilise the maimai DX cabinet's centre touch sensor. The Expert chart (Lv. 10+, 10.6), designed by 鳩ホルダー (Hato Holder, "Pigeon Holder"), serves as the mid-tier introduction with 61 Slide and 49 Touch notes across 525 total notes. Both はっぴー and 鳩ホルダー are established maimai chart designers with prior credits across multiple DX versions.
