These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
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".
