In recent days, we have had reports that the player does not goto the next song in the playlist under Chrome version 64.
After some investigation, we found that the problem is because somehow these mp3 files are not compatible with the latest version Chrome 64.
Chrome 64 does not trigger the HTML5 video
ended event for these mp3 files, so the player can not jump to the next song in the playlist.
To fix the problem, you can use the open source freeware Audacity https://www.audacityteam.org to re-encode your mp3 files. You can open your mp3 file with Audacity then export it as MP3, the problem will be fixed.
