UPDATED IN ORDER 5/22/2013: Olly Murs, Fall Out Boy, fun., Macklemore,  ... Updated each week to reflect the biggest hits of the week based on a variety of criteria that I use including iTunes sales, YouTube plays, broadcast and internet radio airplay, and more. My countdown does not necessarily match those from the commercial outlets such as AT40 and Billboard. I believe mine is more representative of true popular music from fans than the corporate versions. NOTE: Some tracks are not included if they are not available on MySpace.
