This has been requested before…these were the results of that conversation
So support on that may be far off as implementation seems complicated.
Unfortunately for now i think the best you may be able to do is word by word lyrics where you use each timestamp to denote a word but then your lyrics would be very quickly flashing / dashing across the screen. So id suggest you wait it out. The dev didnt say no
In the meantime you could upload a few of your files with these types of lyics so that the developers can potentially figure out how they work, any quirks in your files they should account for and a bunch of other back end stuff im too out of the loop to understand.

Personally I’m impressed theses lrc files even exist I thought finding a standard synced lyrics file was rather tough to begin with.
