Despite its cheerful clapping and festive melody, this work chills you with the cynical message of its lyrics and the eerie atmosphere of its music video.

No reply yet, kana? 💦❓ Old-man texting style 😁❗️Uncle Yoshimoto
Unlike the mainstream Japanese music scene, the Vocaloid community tends to be more welcoming to novelty/comedic songs.
Among recent meme tracks, many of you might immediately think of the particularly striking “Still Waiting for Your Reply?💦 The Middle-Aged Man Texting Style😁❗️,” right? While this piece features the trademark rapid-fire delivery typical of Vocaloid, its vocal range isn’t especially wide, nor does it have extreme melodic leaps.
As a novelty song, it’s a guaranteed crowd-pleaser, and on top of that, it’s relatively easy to sing—making it a smart addition to your repertoire.
