8) Kaputt- Destroyer
9) Reflektor- Arcade Fire
10) Art Angels- Grimes
11) Currents- Tame Impala
12) Teens of Denial- Car Seat Headrest
13) St. Vincent- St. Vincent
14) Channel Orange- Frank Ocean
15) Yeezus- Kanye West
16) Lonerism- Tame Impala
17) Take Care- Drake
18) No Cities to Love- Sleater-Kinney
19) Days Are Gone- HAIM
20) Summertime '06- Vince Staples
21) Teen Dream- Beach House
22) Human Performance- Parquet Courts
23) In Colour- Jamie XX
24) Bloom- Beach House
25) Parallax- Atlas Sound
Honorable mention: Any of Kurt Vile's. They're all very good.
I'm at least tuned in enough to know almost all the names on this list, and I've listened to maybe a third of it. I like some of it a lot. The Car Seat Headrest album is good.
I still love "discovering" new music, but increasingly it's not new at all -- just new to me.
I grew up on 80s New Wave. For a long time, that was still 90% of what I listened to. Then I decided I should really make an effort to listen to new stuff. I got a lot of popular indie stuff like Frightened Rabbit, Arcade Fire, Beach House, Best Coast, etc. Ultimately, I concluded... meh.
There's newer stuff I do really like -- Butch Walker is great, Ryan Adams, Jason Isbell, Sturgill Simpson -- but a lot of what I'm told I should like seems really weak to me.
At the same time, though, there are decades filled with great stuff I've never listened to.
That's the music I'm discovering now. Why should I keep trying to convince myself Arcade Fire is any good where there are still like 20 Van Morrison records I haven't listened to? Right now I've got Spotify fired up and I'm listening to Wayne Shorter's Blue Note collection. Never listened to him before. He's really good. I was in New Orleans over Spring Break and picked up an Allen Toussaint record. Holy shirt, he was brilliant. I've been going down that rabbit hole for the last two months. Curtis Mayfield. The Faces. The Zombies' "Odessey and Oracle." Dennis Wilson's "Pacific Ocean Blue." The O'Jays. George Harrison's 70s stuff.
