docs: Load the list of songs.
  
          Note that this only loads a list of songs that this artist was the main
          artist of.  If they were only featured in the song, that song won't be
          listed here.  There is a list on the artist page for that, I just
          haven't added any parsing code for that, since I don't need it.
