Grammy awards usually miss out huge swathes of the best music in a given year. The whole indie sphere is basically excluded unless something breaks through to radio, despite typically being some of the best reviewed and artistically interesting music out there. Particularly for rock, as pop is obviously gonna be popular and a lot of great and creative hip-hop does have broad appeal. Are we supposed to believe that the best rock bands of the 2000s were Foo Fighters and U2? If you were to just look at Grammys won, that's what it would look like. That time period was crazy for indie music too - like 2004 to 2010 there were probably hundreds of indie rock bands getting great reviews and playing sold out shows, some of them eventually in arenas... but it was the exception to see any of them nominated. The Oscars have their share of problems too, but to their credit you'll still see movies 90% of people have never and will never watch win multiple awards because they're just that good. Music should be the same.
I also think it's silly when an award is given because someone is "due", when the thing they win for isn't actually the best of the year. Like Leo winning his Oscar for that bear movie, and Kendrick winning a pulitzer for Damn (should have been TPAB).
