I have a M3U playlist that has URLs for some MP3s around the web. It's on a server so I can open it on other computers and my iPhone. Unfortunately, all the players I've tried don't let me hit the "next" button to go to the next song in the playlist. Is there a way to specify that ability in the M3U file? Or, if not that, can I make ...
