Those who are archive.org fans….write them and ask them to find a coding team to create a Sonos service app to link and browse through the Sonos app.  I’d gladly pay $10 to have that service and catalog on Sonos.  Relisten is great but is only maybe 20 pct of the archive.org content.   This needs to happen, people will pay archive.org for the app, they are always trying to raise money.
