Comment:
The big problem here is that there is no default playlist format on the
gnome desktop yet. We should be promoting free+open file formats and
therefore the default playlist should be XSPF.

However creating a playlist that's not supported on Totem/Rhythmbox is a
bit of a problem. Because serpentine would appear to be broken because
it would not cooperate with other applications.

But going back to one of the problems posed here. Serpentine tends to be
somewhat spatial, in the sense that it remembers the files you put after
closing it. The playlist exporting is a mere accessory, thus when a
users is exporting it knows what it's exporting for. It does not pose
the user with the need to save your project because 90% of  the times
you use a burning application is to burn one layout (like K3B).

This is exactly the same problem text processors face or image
viewers/editors. The user _will_ learn which file formats his/her
favorite program supports. If we lived on a perfect world there would be
no need to for this, but let's face it, there are more then one
application for the same thing and more then one platform.

To sum it up, choosing a good default is a hard decision if we want to
promote open file formats in the same time. Generating the format by
extension seems to me the most ellegant to accomodate users that already
know which playlist format they want to create.

One thing that this problem reminds me is that Serpentine should
remember the last playlist format chosen.
