6. Open the created playlist

Expected behavior

Screenshots/Screen recordings

No response

Additional information

The approach for implementing this display option is the problem here. It overwrites the title inside of the entity object after loading. If this entity is then resaved, the filename gets persisted and not the actual title.

In general, actions that don't alter a track shouldn't alter the entity object. A better approach would be an extension method on the entity which gets the filename to display.
