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: "Don't You Evah" is a cover of "Don't You Ever" by The Natural History. In fact, because the release of The Natural History's album People That We Meet was held back for a few years for contractual reasons, Spoon's cover came out before the original, and The Natural History version was first released as a B-Side of the Spoon one. Of course, it went on to become one of the band's most well known songs.
"Me And The Bean" is a cover of The Sidehackers, another Austin band.
