This week, the Top 20 Songs airing on our weekend radio show are a mix of older and newer jams. Both Matchbox 20 -- we are so pumped to hear them on the radio again -- and Gym Class Heroes are making debuts on PopCrush's Top 20 Songs countdown, with their latest singles 'She's So Mean' and 'The Fighter' coming in at No. 18 and No. 20, respectively. Meanwhile, Carly Rae Jepsen holds on to the No. 1 position, while One Direction, Maroon 5, Gotye and fun. keep up their Top 5 reign.
