Probably because an XML format is sufficient for most uses. I've seen
XSPF used in many places - a list is here http://wiki.xiph.org/XSPF
and more complete here: http://www.xspf.org/applications/ .

However, if you want to use XSPF in JSON, it looks like JSPF is the
way to go. I've also found this: http://gonze.com/xspfgate/ which is a
conversion service from XSPF to JSPF and there's also this
. But it seems most of the discussion/development about JSFP was in
2008 when Chris Anderson wanted it for his grabb.it company (which
doesn't seem to have survived).

If you have a need for JSON and seeing that XSPF is a widely used
format for playlists, it seems to me using JSPF is the right way
forward. Also, as per your concerns, JSPF doesn't need any
specification of its own, since it's just a different representation
