Well, if you look at the
US Year-End for 2008, the whole thing was mostly Hip-Hop/R&B; but in 2009, Just Dance, Poker Face, Boom Boom Pow (
biggest hit of the year), I Gotta Feeling (and Sexy Bitch, if you want) charted strong and the following years a string of Dance/Club records are dominating the charts (
Tik Tok being the most successful song the year after along with other Dance/Club). 2011 rolls by and the
Year-End is still dominated by Dance/Club songs. That's all there's to it.
