[Improvement] Add an icon for files without lyrics

[nulledone]

It could be like the show lyrics button with a red stroke over it.

Making show lyrics icon persistent would be the best option.

Expected behaviour:

File with lyrics - current icon

File without lyrics - current icon with stroke. When tapped, it can toast something like 'no lyrics found'

Hello! During playback on the now playing screen there is a lyric icon, and for songs without lyrics this icon does not appear.

Вut I'll still think about it.
