[Bug] Same track from same artists registered as two different songs

[SirMartin]

Describe the bug
Artists have the same song but published on the single and also later on the full album. I want to register just once the song, because it is exactly the same song. This happens at least with Spotify.

To Reproduce
Steps to reproduce the behavior:

1. Play a song from a single (fx. https://open.spotify.com/track/0GARcbxLIOmzrs0lHpuvmi?si=abf785d935ea47a5)
2. Play same song from the album (fx: https://open.spotify.com/track/3V3H0j55mS4OgXiOT7vpmR?si=03feaf3b6df144af)
3. When visit Koyto I see two different tracks, but it is the same track, same title, artist, and duration.
4. I even tried to merge them on Koyto, but the next time I listen them , split to two different tracks again.
   Expected behavior
   A clear and concise description of what you expected to happen.

With this song in particular, after merge them first time, it creates two different new tracks.

And two of them live in the same album, but as different tracks.

Version (please complete the following information):

• Koito version: v0.1.7
