Did you know that the most popular genre is rock? It outperforms its closest competitors (which are pop and classical with almost equal popularity) 1.5 times! Jazz holds the 4th place and after that there's an abyss between it and folk, soundtrack, country, etc. It's interesting that rock does not include new wave, rock & roll, classic rock, folk-rock, all sorts of metal (which are also rock, but considered different genres here, on cdtrrracks.com). So, rock is the most popular music of this planet!
