Very high CPU usage

[Shinmera]

I recently was wondering why the CPU usage on my Linux laptop was so high despite nothing much running, and discovered that rescrobbled was eating a full core.

I had Elisa open but not playing anything, and Vivaldi (a Chromium-based browser) with a video playing. The log just says:

Mar 13 22:14:02 linux1 rescrobbled[1590822]: Player Elisa stopped, looking for a new MPRIS player...

but nothing after that, which would be when I played the video and was noticing the high CPU usage.

Rescrobbled is 0.7.1.r8.g1db952f-1, Linux is Arch 6.13.4-arch1-1.
