Moomin was a tv series made by a Finnish author and it was turned into anime TV show back in the day. It is even today still popular in Finland and in other places as well. It told about these Moomins who lived in a valley and what happened in their daily life. The music in it was pretty good for its time and these songs were made by Sumio Shitori.
Snufkin was this character who was constantly moving and travelling from place to place, and this theme resembles how he leaves every Autumn from the valley and always comes back after the winter.
Moomin is part of my childhood, and this track is one of my favourite songs from the Moomin series. A lot of nostalgia on the line for me, but even today I think the music made by Sumio Shatori is very iconic and can work as remastered music.
