I am rebuilding my YouTube Music organization from scratch.

Task:
Propose at least 3 different playlist split strategies for my full liked songs library.
Then choose the best one.
Then assign songs into the final playlists.

Important rules:
- Use the exact song title text exactly as provided
- Use the exact primary artist text exactly as provided
- Do not rewrite titles
- Do not shorten artist names
- A song may be assigned to multiple playlists if it genuinely fits multiple moods or contexts
- Do not force every song into multiple playlists
- Playlist names should be practical and reusable, not overly niche
- For each playlist, add a short natural-language description of the vibe/mood
- Return only valid JSON
- Do not include commentary outside JSON

Return JSON in exactly this shape:

{
  "strategy_options": [
    {
      "name": "Option name",
      "description": "Short description"
    }
  ],
  "recommended_strategy": "Option name",
  "playlists": [
    {
      "name": "Playlist name",
      "description": "Short vibe/mood description",
      "songs": [
        {
          "title": "Exact Song Title",
          "artist": "Exact Primary Artist"
        }
      ]
    }
  ]
}

Now classify these songs:
