It should be possible but I’m guessing that the final result would not be as seamless as Stremio. If you’ve ever tried using Lidarr you’ll realize that a lot of music just can’t be found in public trackers. Even if it is available, the file name formatting is not as consistent as it is for TV or Movie torrents. Since songs are so much shorter than other forms of media that adds a lot of friction. Using a streaming service, self hosted or otherwise, is probably the better solution anyways.
