Oh, my backlog is still horrific. I struggle to go through albums, so that's why I check out singles and lone songs instead lol.
RYM/RateYourMusic is an online music archive where you can rate and categorize music releases. It's also known for being pretentious/hipster-y, but I enjoy it. Better getting songs through there than Billboard or the radio.

AlbumoftheYear is a similar site.
As for shows this year, I've watched Idol I and (finally) the Total Drama Reboot. I've got plenty of backlog in this area, too. I've been meaning to watch Scarlet Heart since Seohyun and IU are in them, I'm just apprehensive about K-Dramas. They're not usually my thing. Does it have a lot of K-Drama-isms in it?
Don't even get me started on my reading backlog. I went through my old college bins and got the books out so there's even MORE books staring me in the face right now. Might pick up the vocabulary one since I want to get into linguistics and language. Recently, I've been going through Wiki articles about different extinct languages and common misconceptions.
