What the F happened to bands

This is something that has bothered me for a few years now and maybe already spoke about here, but seriously where the fuck are all the bands now? Just looking at charts for the best part of the last five years or more its almost solely full of single artists. Are we truly at a tipping point where rap and RnB are the forefront of music? (disclaimer: whatever that in the charts is now is *not* what I consider rap or RnB) I understand there is some electronic and Ed Sheeran thrown in there but where are the groups?!

Are rock/punk/metal and with it bands in general all now of a bygone age much like how they took over from folk and orchestrated music?

​

Edit for clarity: I'm not trying to find quality music by looking at the Top 40. I'm commenting on the decline of bands in the top 40 over the last decade.
