Covered Up: Most of the Cover Versions mentioned on the main page. Special notice goes to Paul Pena's "Jet Airliner", whose original 1973 recording was shelved and left unreleased until 2000 - Miller heard it on a bootleg recording and liked it a lot, and his cover ended up paying Pena's bills for a while.
On the other end of this, many younger listeners are probably more familiar with Seal's rendition of "Fly Like an Eagle" from the Space Jam soundtrack than with Miller's original.
Epic Riff: "The Joker", "Take the Money and Run", "Fly Like an Eagle", "Rock'n Me", "Jet Airliner".
Mondegreen: "The Joker" is a frequent source of these.
Painful Rhyme: "Take the Money and Run" (Texas/facts is/justice/taxes), "Abracadabra" (abracadabra/grab ya).
