XSPF: XML Shareable Playlist Format Logo

JSON

JSPF is JSON XSPF. The definitions of JSPF fields follow from the XSPF specification, but the expression uses Javascript.

This is documented by example, per the JSON below. The example below was engineered by (in order of how many contributions they made) Sebastian Pipping, Chris Anderson and Ivo Emanuel Gonçalves.

A simplified version, without the full range of features:

 {
   "playlist" : {
     "title"         : "Two Songs From Thriller", // name of the playlist
     "creator"       : "MJ Fan", // name of the person who created the playlist
     "track"         : [
       {
         "location"      : ["http://example.com/billiejean.mp3"], 
         "title"         : "Billie Jean",
         "creator"       : "Michael Jackson",
         "album"         : "Thriller"
       }, 
       {
       "location"      : ["http://example.com/thegirlismine.mp3"], 
       "title"         : "The Girl Is Mine",
       "creator"       : "Michael Jackson",
       "album"         : "Thriller"
       }
     ]
   }
 }

Comprehensive example:

 {
   "playlist" : {
     "title"         : "JSPF example",
     "creator"       : "Name of playlist author",
     "annotation"    : "Super playlist",

           {"http://example.com/rel/2/" : "http://example.com/body/2/"}
         ],
