This is a movie I saw at a film festival in 2015 or 2016, so it's from the 2010s. A very surreal Japanese movie where a guy falls in the sewers and meets these weird CGI animals. He befriends one of them, who sings a song to him. Guy records the song, it becomes a massive hit and he becomes a big pop star, but he never tells he got it from his animal friend, and his conscience starts to weigh on him. In the end the animal grows into Godzilla size and attacks the guy during a big concert of his. I'm sure some of you must know this one?
