Is your feature request related to a problem? Please describe.
Currently, when adding tracks to playlists, they're always appended to the end. But I want newly added tracks to appear at the top of the playlist so that I can hear my latest additions first. This forces me to manually reorganize the playlist.

Describe the solution you'd like
Add a user preference for playlist addition behavior with two options:

1. Append to end (current default behavior)
2. Insert at beginning (new tracks appear as the first items in the playlist)

This should apply to:

• Single tracks added via "Add to Playlist"
• Batch additions (albums/artists/other playlists)
• Drag-and-drop operations

Describe alternatives you've considered

1. Manually sorting playlists after adding - time-consuming for large playlists
2. Creating new playlists and re-adding tracks in reverse order - creates redundant copies
3. Third-party playlist editors - breaks workflow and requires exporting/importing

Additional context

• Implementation suggestions:
  • Global setting: Preferences > Playback > "Default playlist addition position"

Apps

• NetEase Cloud Music:
  The default action for "Add to Playlist" inserts tracks at the beginning of the playlist.
• QQ Music:
  By default, "Add to Playlist" places new tracks at the top of the playlist.

Thank you for creating such a wonderful music player! It perfectly solves almost all of my needs.
