Subject: [PATCH] fix: Potential fix to #485

- This ensures no duplicate entries when importing an M3U playlist. Order should also be preserved.
- This assumes the issue is caused by duplicate tracks in the M3U file, which I guess could happen if the playlist it was generated from supports duplicate tracks.
