The idea of DJ-as-selector/curator (rather than producer or 'personality') has had a resurgence in the electronic music scene over the last few years. The tastemaker DJs on stations such as Rinse FM and NTS are increasingly reaching wider out or further back to find old gems and weirder music to build into increasingly eclectic sets, and I think this has been driven partly by the mainstreaming and homogenisation of electronic music culture into "EDM" in the US, but also as an antithesis to the machine-made reductiveness of Spotify genre mixes.
As a regular club-goer here in Europe, it's no longer enough for a club DJ to merely play one genre all night long -- a crowd expects to be surprised and entertained.
If you're looking to widen your scope, the electronic music community has some great resources out there, and you can dive into any of these and find something utterly new and exciting without much trouble:
