I can recommend PowerAmp. I've been using it for over a decade and it's been pretty happy with updating my 20,000+ song collection and my 1,000+ song playlist that I sync with an graphical ssh/rsync wrapper (although I've actually been switching to an rclone wrapper, RoundSync, in the last few months). My personal favorite feature that I got addicted to back when I was using Amarok in KDE 3 was the ability to have a playlist and a queue that resumes to the playlist when exhausted. Then I can listen to an album in order, and then go back to shuffling my driving music playlist when that's done.
