DJ Earworm's United States of Pop releases continue with "Don't Stop The Pop"-- a somewhat sloppy dance floor cat fight with the year's hit songs including Katy Perry, Rihanna, Tiao Cruz and more. This isn't a criticism of of 2010's Billboard Charts; it's a testament to the difficulties of mash-ups, especially if you have to use certain songs.
