Wonderland Music is the name of the system at Disneyland where you can "Burn your own CD". Essentially it's the reincarnation of DIsneyland Forever, though in this version, the albums are all prearranged, rereleases in fact of old albums. So far the only location for this system is on Main St. in Twentieth Century Music. There are 3 kiosks wehre you can preview a sample of each track in each album, plus all other albums in the store. And yes one of the albums is the "Disney Afternoon" soundtrack.
