The MusicBrainz C/C++ Library by MusicBrainz is a client cover art archive library for developers. Using this library, developers can add cover art capabilities to their applications. The MusicBrainz database contains a huge amount of music metadata, which is maintained by the MusicBrainz community.
Music is what connects all of us together. Music Lyrics are one of the most searched items on the Internet and one would expect that the Lyrics data would be accessible via one or more APIs. We list 8 Lyrics APIs in our directory but in the past this has got into trouble over copyright issues. The MusixMatch API wishes to change all of that by giving you access to 5 million officially licensed lyrics.
