On June 8, 2022, the Napster streaming service overhauled its Web interface, changing the URL format for links.
Old album links look like this: https://us.napster.com/artist/digitalluc/album/float-306172001
New album links look like this: https://web.napster.com/album/alb.306172001
As you can see, there is still a central numeric ID around which a script can build a URL.
The old URLs should be marked as ended on 2022-06-08.
