Hide lyrics overlay when there are no lyrics

First off, great app. Definitely my favorite lyric add on! I'd love the option to automatically hide the "No Lyrics" overlay and just show the cover art when there are no lyrics. I've also had an instrumental song come up with a single line of Chinese characters as the lyrics (Polyphia - GOAT), so the option to turn the lyric overlay off per-song  would be cool too.
