Hello! I've made a cover of Bad Apple!! feat. nomico in 32 conlangs, including popular languages such as Esperanto and Toki Pona; conlangs of mostly historical interest like Bolak, Dutton World Speedwords, Babm and Universalglot; various worldlangs including Sambahsa and Lingwa de Planeta, a few fictional languages (Quenya, Klingon and Trigedasleng); and a fair number of loglangs (Lojban, Loglan, Toaq and Xextan).
I'm not sure how to categorize this, but since the vast majority of the conlangs used fall under "other", I guess it's an "other" topic now :)
