Lyrics plugin for Yatse

One feature I really miss in Yatse is a Lyrics feature inside Yatse or some sort of lyrics plugin. Even a trivial one without scrolling/timing support, using one of the many good lyrics sources out there, would be awesome.
I’ve been waiting for years as I thought that it would eventually come.

For inspiration on what lyrics sources to use and some source code, see the lyrics plugin of the great DeaDBeef audio player for linux.

Use case: Yatse used as the GUI for a headless Kodi installation (used as a music server with an HD Audio card).
