These pages are not real Artist pages, they are named after musicals, movies or a tv series. They should be formatted as Compilation albums or Soundtrack albums, with the artist for each track identified. Each page may contain songs that only appeared on different albums. The ArtistFooter links to Amazon, musicbrainz, discogs, allmusic and iTunes will help find the correct album, real artist and release year. Finally the artist page can be converted into a disambiguation page for the albums (if more than one).
