IPFI is the biggest joke of all time. I mean, who uses them? If you look carefully at Digital Report for 2010 you will see that CrushCrushCrusg song by Paramore (which was released in 2007) making the list of the best selling singles. The song has 0 certifications and it was flop everywhere, yet it made their list. Even Mediatraffic numbers look more accurate than SHITFI.
