ok so i'm a big fan too and have bob's whole collection with extra songs, and those extra songs are the ones confussing me right now, coz i can't find them in this bob official site and i wonder when those songs were published and released by bob.

the songs are:

sign langauge
people putting people down (though i only have a live version)

also, why "I'm Not There" soundtrack is not listed in here, not to mention that bob release a song in that album, song title (I'm Not There)...

so...
