Too many good ones to single out but I am surprised that Prologue / Crunchy Granola Suite hasn't made it yet despite the argument that it shouldn't count as an intro.
That transition from 3.18m to 3.19m on the Hot August Night version is hard to toss.
Dished out some rotten stuff did Noah Kaminsky but his better stuff was with many an intro which carried the song most times was pretty bloody good.
