Hall of Famer
When I was 23 contemporary artists were:
Nirvana
Soundgarden
Pearl Jam
Faith No More
Stone Temple Pilots
Alice In Chains
Rage Against the Machine
Oasis
Supergrass
the Verve
You Am I
To name but a few. A lot have things have got better this century. Music has bucked the trend.
I think it's kind of hard to compare, because the style of music that makes up the mainstream is so different. There's still quality rock bands, but mostly the interest isn't there. I would argue, however, that some of the most mainstream artists of the last decade have put out quality music:
Kanye West
Kendrick Lamar
Frank Ocean
Chance The Rapper
Justin Timberlake
Radiohead are still going strong
Beyoncé
Bruno Mars
Lana Del Rey
alt-J (they're as, if not more mainstream than some of those 90s bands listed were)
Lorde
The Weeknd (Starboy was pretty good, but I'm more so referring to his first 3 mixtapes)
Heck, even bands like The 1975 have put out quality songs. Then you have artists that aren't too far outside of the mainstream putting out quality music. For example:
Foals
James Blake
Glass Animals
Unknown Moral Orchestra
Danny Brown
Lykke Li
Chet Faker
Jungle
FKA twigs
Not necessarily a fan of all of those I listed. Just some names off the top of my head that are pretty major artists that have released quality works; be that LPs, EPs or singles.
