I hope for a fairly quick review of this pr.
If you need it, here's the documentation for the music api https://vodka2.github.io/vk-audio-token/
The work done is not small, there were a lot of tests, all the bugs that were found by users are fixed.

since this pr seems to be active again, how long should I wait before reviewing it?

[Krispeckt]

Idk 😅 but for me personally I'm all set, it's just that I've been informed that the lyric in the vk may still give it with timestamps

[topi314]

you want to rebase this pr onto master, there have been some readme changes

[topi314]

can you also move all your stuff to the bottom and not inbetween existing audio sources?
notably documentation (README) & config

[topi314]

please resolve conversations when you fixed what I asked there, else I need to check every single one of them myself.

not sure where those spaces come from but there is a .editorconfig which should let you simply format lavasrc.

i think this finally looks acceptable to me
