LP don't download anything it just streaming audio, also we use currently ANDROID client and im pretty sure it not affected by throttling, since it providing deciphired links with all provided arguments for just playback audio

Technically it is downloading the song but to memory. Seeing as a download is nothing more than streaming the contents to a file on the disk.

This is the song in question that buffers on my side:

I verified the same doesn't happen on other songs. eg:

The reason why I think this is happening is because probably the speed is throttled

You try play this song on your home PC or on hosting?
Also how does it manifest, because I'm not experienced this issue at all

The n parameter challenge is random based on what I see on the issues there. This is tested on prod server with a gigabit connection so bandwidth is rarely an issue.

Official YouTube app on android don't use any n parameters in videoplayback links, so I do not think that Google would like to limit Internet speed in its own application

Will be added in 1.3.98
