about the song data switchboard:
Song data switchboard is a web service by In1woord that helps to quickly find data about songs and artists on a variety of music related web sites. A song can be either entered manually or selected from a playlist you provide.
Song data switchboard is built on the ruins of Ome Piets Überapparaat, a tool I once made mostly for the benefit of listeners of a particular radio show of which the playlists are now no longer online. I expanded and adapted it to accept Spotify playlists as input.
Here are some playlists to try:
N.B.: This list is based on this playlist, linking all songs in it with the song data switchboard.
