I think there's plenty of very adventurous stuff taking place - but if you're expecting all this adventure to be reflected in the charts you'll likely be disappointed. The pop charts represent just the tiniest sliver of today's (and yesterday's) music.
There's also the issue of streaming now being counted towards chart "sales" and this has resulted in a very different set of results to anything that the charts has previously enjoyed.
I quote from this article
http://www.bbc.co.uk/news/entertainment-arts-36794105:
"Drake has been hogging the limelight for three months.
On Friday, the star's single notched up a 14th week at number one - meaning he could soon break the Bryan Adams barrier, and become the UK's longest-running chart topper.
But behind that huge success lies another story, because One Dance isn't the best-selling record of the last seven days. It isn't even in the top 10.
In fact, Drake's single only topped the sales-only chart in the first three weeks of its reign. It's only the inclusion of streaming data (where 100 plays count as one sale) that has given him a lock on the number one spot. And that's something that's starting to worry the music industry, because now that the charts measure consumption rather than purchases, they have practically ground to a halt.
In the first six months of 2016, there were 86 new entries in the UK singles chart. Ten years ago, that figure was 230. "
The highlights are mine. The article is well worth a read if you're interested in chart music.
