Search Genius for a song and retrieve its metadata, understanding the API's lyrics limitation

Steps

1. Call GET /search?q={keyword} to find candidate songs matching a keyword query
2. Call GET /songs/{song_id} to retrieve detailed metadata for a specific song from the search results
3. Do not expect a working GET /songs/{song_id}/lyrics call to return full lyrics text directly from the API
4. Instead, use the song's Genius URL from the metadata response and fetch/parse the lyrics from that page separately if lyrics text is required
5. Cache song metadata locally since repeated lookups of the same song don't need to hit the API again
