Problem

Spotify is enforcing new redirect URI validation rules starting April 9, 2025, with all clients required to migrate by November 2025. This change means our current configuration using http://localhost:8888 will no longer work.

Changes from Spotify

According to Spotify's new requirements:

When using a loopback address, explicit IPv4/IPv6 addresses must be used instead of localhost
Allowed redirect URI examples: http://127.0.0.1:8888/callback or http://[::1]:8888/callback

Required Actions

Update documentation to instruct users to set the redirect URI to http://127.0.0.1:8888 (or their preferred port)
Update any code references to the redirect URI
Update configuration examples in the README

Impact

This breaking change affects all users who create new Spotify apps after April 9, 2025, and will affect all existing apps by November 2025.

Priority

Medium: Required by November 2025, but already affecting new app creation.

This change is essential for continued use of the Spotify API. More details can be found on the Spotify Developer Blog.
