I might try and do a "Music Plum listened to this year" even if it'll be a little sparse because I don't have the time or energy to be full DJ brain
Side note, the real hardest part of DJing is keeping up with the music. Because it's basically your job to know all the nooks and crannies of the genres you mix. And there's a lot, a lot, a lot of fucking music out there now, and usually a lot of people making it.
