Overview
39 is a collaborative VOCALOID track by sasakure.UK and DECO*27, commissioned to celebrate the fifth anniversary of Hatsune Miku's release. Its title is a deliberate numeric pun: 39 can be read as sankyuu (thank you) in Japanese goroawase wordplay, and it also evokes Miku, a reading so common in VOCALOID culture that the lyrics cheekily remark, "あれ、なんだかアタシの名前みたい（笑）" ("Hm, it almost reminds me of my own name… lol"). The song first appeared in maimai PLUS on March 18, 2013, and has since become a mainstay across SEGA's rhythm game ecosystem, receiving Standard and DX charts across multiple maimai versions as well as ports to CHUNITHM and オンゲキ. Composition is by sasakure.UK, with arrangement and programming by both artists, lyrics and chorus by DECO*27, guitars by DECO*27 and yuxuki waga (s10rw / fhána), bass by Scop, drums by kous, and keyboards by 40mP. The music video was produced by hie / akka and のん. At 175 BPM and a compact 1:56 runtime, the track balances a driving electronic pop-rock sound with Miku's characteristically bright vocal delivery, its lyrics expressing gratitude toward listeners and fans, a sentiment that mirrors the celebratory occasion of its creation.

Trivia
- 39 was composed for and first released on the Hatsune Miku 5th anniversary compilation album 初音ミク 5thバースデー ベスト ～impacts～ (2012) before being added to maimai PLUS in March 2013.
- The title 39 carries a deliberate double meaning in Japanese goroawase: it can be read as sankyuu (thank you) and as Miku, the latter being a standard reading in VOCALOID circles. The lyrics directly nod to this by remarking that 39 sounds like Miku's name.
- The Re:MASTER Standard chart, added on July 5, 2019, was the final regular chart added to any maimai title before maimai でらっくす launched, and the last Standard-only chart until maimai でらっくす Splash.
- The DX chart set was added at maimai でらっくす launch (July 11, 2019) across all regions simultaneously.
- At the lyric line 声に出して 39! (Speak up: 39!), the Standard Re:MASTER chart places slides from lane positions 3 through 8 moving toward position 1, visually forming 3→9, a chart-side tribute to the title's numeric wordplay.
- The Re:MASTER chart (difficulty constant 13.4) is widely considered a score-farming chart in the competitive community; its Break-note sections reward careful study with high scoring potential even for gold- and silver-rank players.
- All CHUNITHM charts for 39 feature notecounts ending in 39 (339 / 539 / 939 / 1339), and オンゲキ charts include 39 in their notecounts (e.g., 353/39, 372/39).
- Production credits include a rare collaboration of Vocaloid-P talent: guitars by DECO*27 and yuxuki waga (fhána), bass by Scop, drums by kous, and keyboards by 40mP.
- 39 was removed from Chinese region (舞萌 DX) cabinets starting with 舞萌DX 2023, then revived on December 15, 2023 with other updates.
- The song's in-game genre changed over maimai versions: it debuted under VARIETY in maimai PLUS, moved to niconico from GreeN PLUS onward, and settled into niconico & VOCALOID from PiNK onward.
