Playlist import process fails

[NomadicDaggy]

Somehow this still doesn't get caught:

  File "/usr/local/lib/python3.9/site-packages/sqlalchemy/engine/base.py", line 1900, in _execute_context
    self.dialect.do_execute(
  File "/usr/local/lib/python3.9/site-packages/sqlalchemy/engine/default.py", line 736, in do_execute
    cursor.execute(statement, parameters)
psycopg2.errors.UniqueViolation: duplicate key value violates unique constraint "ix_tracks_spotify_id"
DETAIL:  Key (spotify_id)=(6pTDPaMcN5KSYD8hJ1uWId) already exists.


The above exception was the direct cause of the following exception:
