Feature request: Additional low bitrate stream

[middling]

Type: Feature request
Priority: Low
Description:
The current stream bitrate is too high for reliable playback on oversatuated 3G/4G networks.

The docs say the streams are 128kbps, but a curl -I shows them to be 256kbps. I used to be able to listen when on mobile networks so i believe the bitrate increase happened sometime in the last 18 months or so.

If the increased bitrate is intentional and not a misconfiguration i'd like to request a lower bitrate MP3 stream to allow those on limited bandwidth connections to listen.
