Describe the bug When I connect to my Navidrome instance, which has a lot of songs, after a few seconds the rate limiting kicks in and causes errors in the requests, which shows an alert for each request and makes the application completely unusable.
Navidrome introduced rate limiting because of performance and rate limiting issues on external APIs, when too much album images are requested, see https://github.com/navidrome/navidrome/issues/2130 and related settings https://github.com/navidrome/navidrome/blob/bcab3cc0f908a01ebb99f9f6d0bfb37fadbd95bf/conf/configuration.go#L86-L88. The rate limiting is enabled by default.
To Reproduce Steps to reproduce the behavior:
Expected behavior Application should still be usable, and respect the rate limiting (if possible). Maybe the 429s can just be ignored for now.
