The mainstream pop music landscape can be a noisy blur if you're not an aficionado (or a 12-year-old girl). Anyone who says that a lot of chart topping hits don't sound similar to each other is just delusional, let's be real. Whether you're a fan of the stuff, or just like a healthy dose the super-catchy crack that everyone's always on about, you'll love DJ Earworm's annual smushing together of the biggest songs of the year. I personally loved a fair few of these songs this year, but I won't name names. Just listen.
