drakes influence is colossal (and i think would include things like the weeknd)
whoever started the young thug/fetty wap autotune sort of rap-singing thing also deserves credit for creating what is def something that never existed
trap beats, no matter how dull now, are def of this era
then there's the influence of edm
so there def are things that are relatively new, and most definitely of this era. its more that these things are in service of values that are the status quo, and def not underground, or anti-mainstream (whether by default or deliberate). while i found the whole retromania discussion interesting, and not without cause, at the same time you had that, which has more or less become part and parcel of modern pop, there was equally as many things which were 'of the moment' happening. i think now the development is both slower, and more incremental. there is a greater need for novelty and new product and market presence, etc etc, but this does not include as high a need for innovation.
i dont pay enough attention to indie stuff to really track whats been happening there. but obv the xx have had a great sweeping influence, that kind of overlaps with burial, but i think more coincides with a wider trend for great seriousness and earnestness, and great, rigid sadness in pop. you can even include future in this, as being another rapper overtly keen to show how fucking sad he is all the time, while not really relinquishing raps bravado.
