The Shins, Vampire Weekend, Fleet Foxes. I have no idea if you'll like them, I don't know how to properly recommend music but I can't stop listening to these.
I like Vampire Weekend, but from what I've heard (most of their first two albums), their songs all sound very very similar to me. I thought A-Punk was amazing when it was released first, but I got a little discouraged by each subsequent single, because I felt I was just hearing A-Punk again.
Oxford Comma is a great song though, and the video by Richard Ayoade is a nice bonus.
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that reading the sequences makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
