Music APIs encompass a variety of services, including online song streaming, concert information, download stores, song lyrics, artist, label, song, and album data & metadata, reviews, playlist services, music theory, music composition, free music, band operations, and touring bands information. Developers looking to enhance their music applications can start by checking out the Music category on ProgrammableWeb.
