Steven, excellent work with the integration!
I did some testing, please read below.
In order to check whether Minilyrics works properly I unticked all lyric providers in Musicbee. But when I restarted the first 2 lyric providers are ticked again. Bug?
In Minilyrics I have enabled "Save lyrics in mp3 file" under Preferences>Lyrics. It also saves the lyrics (.lrc) to C:/Lyrics by default which can't be disabled it seems. When I play a track that has no lyrics Minilyrics first searches then downloads and embeds the lyrics automatically. But at the same time Musicbee also searches for lyrics and it displays in its lyric window(due to the bug I mentioned above, otherwise it will not show any lyrics if no lyric providers are selected). What Musicbee should be doing here is give priority to Minilyrics first. If Minilyrics finds lyrics, Musicbee should refresh the lyrics window and display it. If Minilyrics doesn't find any lyrics then Musicbee should search it's lyric providers.
With regards to auto downloading lyrics not working for you, well it works fine for me(unregistered version). But I found that auto download doesn't seem to be working when the track already has unsynchronized lyrics embedded. Same problem in Winamp as well. There is an option in Minilyrics which I have set to "yes"(Preferences>advanced> Lyrics Download: Try to download synchronized lyrics (.lrc) even if having local unsynchronized (.txt) lyrics)
But it doesn't seem to be doing the job right. So I guess this is a Minilyrics issue. Other than that auto download should work. I hope you're using the latest version.
I checked the new build. Show Minilyrics option works perfectly but isn't there a way to hide the Minilyrics window?
This is what I'm trying to do; I want Minilyrics to do the searching and embedding of lyrics but want Musicbee to show the lyrics. I don't want to have the Minilyrics window open. Minilyrics should start with Musicbee but stay hidden. So that possible ?
If I could set a hotkey to toggle the visibility of the Minilyrics window that would be great!
Another issue: Minimizing Musicbee doesn't minimize Minilyrics. In Winamp when you minimize it, Minilyrics also minimizes. It's like it's part of Winamp.
