Musixmatch

Musixmatch answers lyric queries against a licensed catalogue that the record puts at more than 20 million songs. A search can begin with a title, an artist, an album, or a half remembered fragment of a line, and the matching words come back in the conversation.

Results are text rather than audio, which fits two situations in particular: pinning down a track from the one phrase that stuck, and reading along while the music plays somewhere else. Queries are handled conversationally, so a follow-up about a different song or a specific verse continues in the same thread. The catalogue is described as global, and the app is published by Musixmatch spa.
