I absolutely love 季路 by Aimer. It was written for the Japanese dub of the Mo Dao Zu Shi donghua originally in Mandarin. I think it's wonderful that the donghua gained so much popularity that it got translated and then had an ost sung by Aimer!! Like wow!! It's a heavy weight show for sure, star power wise, the osts it got were amazing. I am a donghua truther. Lyrics wise, I think the song is so beautiful with the descriptions of time passing. It feels like its written from Lan Wangji's perspective as he is in the pristine realm of the Cloud Recesess. And then the chorus hits where time is going but maybe a piece of him is lost in the past, frozen in the never ending winter, "even warmth feels far away". The chorus also starts speeding up, the time and seasons suddenly flow by so quickly from the nexus of where it all started. Like how time passes quicker the older we grow from moments we remember.
Objectively, 大鱼by Zhou Shen is a phenomenal song from the animated movie Bigfish and Begonia. It's about letting people go because they are meant to be elsewhere, which was the main thematic message of the movie and it was portrayed in many ways throughout the film and particularly the climax. I like this song because it put Zhou Shen on my radar and his voice just elevates it and you can feel the soaring fish in the sky.
