To add a bit more detail about playllists:
I believe that M3U playllists are specific (proprietary?) to Apple.
And, I’m guessing that the earlier, no longer supported playlist mentioned above, is
NOT based on any Industry-standard.
[ I tried building some html-5 video-tagged webcode to play with playlists, and found that
M3U wasn’t supported by some of the more common browsers, so I stopped development of that webpage. ]
