As I said before, I tested multiple files on multiple players, here another example:
Erasure - A little respect
Positive offset: PA & Musicbee 1700
Negative offset: Plexamp, Oto Music, Musicolet, Subtitle Edit (Windows), Swingmusic -1700
My workflow was edit lrc files in Subtitle Edit cause is much quicker and easier, at least 50% of my entire LRC library was downloaded with the Foobar lyrics plugin and Deezer lacks in lyrics terms, so I had to edit a lot of them.
Recently I found a source to download lyrics with more accurate timecodes, but replace every file one by one? (around 8k files) Nevermind. So a global invert option is the best solution here to keep synced lyrics on multiple players, I share my music library with family and friends through Plexamp and for personal use I prefer Swingmusic to stream music (cause Plex lacks multiple artist).
