I voted for 2010s, but mostly because I couldn't think of too much that I've heard this decade that would rise to the level that I'd miss never hearing again. I don't really dig too much (and never did when I was younger). Even past my formative youth, if you ask me what I'd miss from the 2000's, I could at least rattle off some albums by the likes of The White Stripes, Black Keys, Radiohead, OutKast, and Wilco.
For 2010s, maybe I'd put something like Adele's 21 or some Kendrick Lamar in that company, but I think I could live without those.
For people saying that there is a lot of great music out there now if you really go looking for it, how do you go about finding it? It seems like everyone uses Spotify, but I've always found the user interface of Spotify kind of terrible. Maybe part of the appeal of the earlier stuff is that I didn't have to go looking for the good stuff. It just kind of entered the zeitgeist (but that might relate more to era of music than the decade's entire catalog).
