The Reocurring Dream - enough said The Jungle Line - the drums, the background chanting, and Joni's little "...the drums, the drums, it's the drums, the drums, the drums" (BTW is The Jungle Line the first known example of sampling and tape-looping in music, cause they seemed totally unique at the time)
The Hissing of Summer Lawns - the little percussion effect which makes it sound as if one is walking on grass God Must Be A Boogie Man - The background choir of institution escapees (Are all those voices Joni's or did she have some of the band fill that in?) The Magdeline Laundries - following of the 90's trend of Joan adding ambient synth layers to flesh out her songs
