I suggest you follow the following steps:
1. In the song playing interface-menu key-Settings-Lyrics-Tick (this lyric is not a downloaded lrc file, you need to right-click the song-Summary-Advanced-click on the lyrics in the computer to add it manually (the content is written by yourself).
After writing, it will be displayed when playing.
(Note: automatic scrolling is not supported, and manual adjustment is required)
2. Install a third-party music player (apk format such as everyday music and cool dog music)
