Music business blog extraordinaire Digital Music News has published some interesting graphics based on Google's new analysis of topics, which is still in its beta stage. The graphs show the measured interest in musical genres from 2005-2015, and every analyzed genre is down except for electronic dance music, which went sharply up, especially since 2013.
Interest in rock, hip-hop, classical, jazz, blues, metal and disco (?) is all sharply down since 2005. Pop music popularity is also down, but only slightly so. It should be noted that interest in EDM seems to have peaked some time in 2014, and has gone just slightly down since then. See all the charts on the Digital Music News post.
