Another reason I hate box sets...
Take the Led Zeppelin box set, where Jimmy Page decided that he would shuffle around all of the tracks, which is just utter blasphemy! I grew up on Zeppelin, and if I'm in a Zeppelin III - type of mood, I want to listen to Zeppelin III straight thru. I don't want to hear the songs all shuffled up. Hell, they even split up Heart Breaker & Living Loving Maid on the box set, and those songs are practially married on the original album.
