Just to make sure I explained myself correctly, I'm not talking about a lyrics search engine: I prefer doing this myself using Minilyrics. I'm referring to a feature to display a LRC file already downloaded. As you said, I can see in MusicBee remote the contents of the LRC files, but, of course, it'd be so much better if we could see the lyrics, without the tags, and the current line could be displayed in a different colour. I prefer this approach, as can be found in MB, as opposed to just seeing the current line and temporarily hiding the rest of the lines of the song.
Hopefully, Steve will be able to help you, as I imagine it'll be pretty much the same code, although there might be other problems to implement this code on the Remote that I can't think of.
In any case, thank you for your great work and for considering implementing this feature.
