Search LRCLIB for tracks by title, artist or album, and get the id needed to fetch lyrics with get_lyrics. Give either 'query' as free text, or 'track_name' and 'artist_name' separately for a narrower search. Results carry metadata only: title, artist, album, duration, and whether plain and time-synced lyrics exist. Use 'duration_seconds' and 'album_name' in the results to tell releases and re-recordings of the same song apart, and 'has_synced_lyrics' to know whether karaoke-style timed lyrics are available before fetching them. LRCLIB indexes tracks by their metadata, so it cannot search for a word appearing inside the lyrics.

Fetch the lyrics of one track from LRCLIB, given the id returned by search_tracks, or an exact artist and title. Set 'format' to "synced" for karaoke-style lyrics with a timestamp on every line, "plain" for the text alone, or "both". Check 'has_synced_lyrics' in the search results first: not every track has timed lyrics. Lyrics can be long, so the text is truncated by default: check 'truncated' and call again with 'offset' set to 'next_offset' to continue reading. Instrumental tracks come back with status "instrumental" and no text, which is a valid answer, so do not retry them. Always cite 'attribution' when showing lyrics to a user.

Look up one LRCLIB track by its id and return its metadata without the lyrics: title, artist, album, duration, and whether plain and time-synced lyrics exist. Use this to confirm you have the right release or version before calling get_lyrics, or to check whether timed lyrics exist for a track id you already hold.
