I noticed on your site that using the default folder and player shortcode, the play of the songs continues to the next song.
That is not happening for me. I notice the buffer will show 1.06 but the player stops at 1.05 and then never advances. No matter which song I select to play, it does not advance, and plays 1/10 of second short.
Is there something you can suggest? I want to settle on your player. I like it best because of the pop-up window and the ability to play throughout the site, uninterrupted.
