I heard A LOT of sad vocaloid songs but my سب, سب سے اوپر ones are Saihate , y to y , Heaven , servant of evil , young girls self harm habit, Ai wo , موسیقی box, regret message, meltdown (listen to the lyrics its a suicide song) , rolling girl. theres prob mare but that's all I can think of right now
Falling Falling Snow سے طرف کی my fave vocaloid and guy of all, Len Kagamine. It makes me cry every time for three reasons: 1. I always cry when Len does, and also theres nothing i can do to help him 2. I can relate to what hes feeling, im heartbroken almost every دن deep down inside 3. theres just always something about songs with slow piano accompaniments that always soothe me and yet make my دل sink all at the same time.
its a beautiful song, and also my پسندیدہ song, and its a great song to cry to, fall asleep to, یا just put on replay when youre walking alone and need some self reflection.
I think "why don't آپ call me yet?" is pretty sad. even if it was not supposed to be (I assume) sad, Rin's desperation to be called back سے طرف کی Len is adorable. And something that most people can relate to.
