"You Mean the World to Me" is a maimai original song produced by Mameyudoufu (豆湯豆腐), a composer signed to the MEGAREX label, featuring vocalist Shully, who also performs under the name うた/コムギ. The track was added to maimai でらっくす FESTiVAL on November 18, 2022, as part of the Metropolis Area 6 unlockable content, requiring players to accumulate 70 km of in-game distance before it became playable. From maimai でらっくす BUDDiES onward, the song is available by default across all regions. Musically, "You Mean the World to Me" is a bright pop track at 180 BPM driven by Shully's energetic vocals. The lyrics paint a playful picture of late-night internet culture, name-dropping "ctrl-V" and lamenting lost originality in copied romantic phrases, before breaking into a sincere chorus. Mameyudoufu has noted that Mega Drive (Sega Genesis) synthesiser sounds are hidden throughout the arrangement, rewarding attentive listeners with retro-console flourishes woven into the modern pop production. The song's jacket artwork credits only Mameyudoufu by name, and the accompanying flavor text (part of the Metropolis world-building narrative) tells a short story about the black-haired princess Kurohime and her attendant Shikuro, hinting at a subtle emotional bond that goes beyond duty. On the charting side, the Expert difficulty was designed by みそかつ侍 (Misokatsu Samurai) and the Master difficulty by ロシェ@ペンギン (Rocher@Penguin), with the Master chart sitting at level 13+ (constant 13.7), a moderately demanding layout featuring 684 total notes weighted heavily toward Tap notes.
