What is the difference between formats when exporting playlists in iTunes?
The available options are plain or unicode text, XML, M3U and M3U8 when exporting a playlist. Is there a difference in "functionality" of a particular format or is it merely a matter of compatibility with a particular platform or software? In particular I am trying to figure out if a playlist from iTunes would be able to be read and "processed" on a flash drive plugged into a late model car stereo which has a USB port.
