I decided to start my own chart. It follows the idea of the Billboard Hot 100 and it can make you see what's actually popular in Italy during the considered week through a combination of airplay and sales. Points of each category are added and they form the chart. Through points' system we will discover which are the hits of the month and, finally, of the year and we'll have certifications.
P.S.: Airplay numbers are estimations based on the charts.
Here we go:
