Are you asking for Lyric to be disabled completely or per-song, I'm not sure I understand what you're asking?
I don't want Lyric to automatically search for Lyrics when I load a tracks or videos to a deck. I have playlist with tracks that have videos linked and others with no Lyrics. Some tracks don't have lyrics because I only like the "ABC - W & L" version and not the "ABC" version. Please add option to disable.
Let's say you have a playlist already created for an event which has a mix of videos, lyric tracks and audio tracks that will display visuals. I don't want anymore Lyrics searched or added to any tracks or videos. Lyrics Function will be enabled while I play this set. For tracks with no lyrics attached or videos I can select Display - Off but rekordbox still searches and added lyrics to tracks and videos when I load the deck with a track. I shouldn't have to go back and forth into settings enabling and disabling Lyrics so it won't keep searching and adding lyrics every time I load a song. Lyrics should only search when "Acquire Lyric when analyzing track" is selected or when you manually search.
Also it would be nice if Display On or Off was a one click action or keyboard shortcut.
