This song, which I find very beautiful, has given me a hard time trying to find it. He appears near the end of the film, at the moment when Light, with the help of one of his followers (the man in the white apron), knocks out L, and Light takes the opportunity to escape and reunite with his gf.

I can't find the complete song on any platform. I thought its name was Skaters Carousel by Sourcerer, however, according to other threads, that doesn't seem to be its name, leaving me even more stuck on the mission to find it.

If anyone has an idea, a fragment, or can simply convert it to audio without all the noise and dialogue, leaving only the melody, I would be eternally grateful, as I truly love it and I hate not being able to listen to this song.

Here's a video clip with the film clip where that melody appears:
