You’re confusing prestigious with rare. Like how there are fewer albums that I’ve literally shat on than albums that have gone platinum, but me shitting on albums is rarer, not more prestigious.
They may have used the word wrong, but getting parodied by Weird Al is actually more prestigious than winning a Grammy. Not because Weird Al parodies are rare, but because he only parodies songs that are actually pretty good. I have trouble believing that if the song were actually bad, playing it on accordion with jokey lyrics would be an improvement. There’s no Weird Al parody of a Nickelback song, that I know of.
but because he only parodies songs that are actually pretty good.
Counterpoint: he parodied Mmm Mmm Mmm Mmm by the Crash Test Dummies.
