The RIYL Music weighted chart recognizes that some stations are simply more "influential" than others.  Stations are assigned a value between 1 and 6.  A #1 chart position is assigned 30 points and then multiplied by the station's weight.  For example, an artist charting #1 at a station weighted "2" is assigned 60 points, while a #1 charting at a "5" is assigned 150 points.  Once RIYL's robots have calculated the chart values for each artist, they simply sort by points.  Long live the king!

 

The RIYL Music unweighted chart feels that every voice should be heard...and believes every voice is equal.  Stations are stations.  No favorites, just pure data.  A #1 chart position is assigned 30 points while a #30 chart position is assigned 1 point.  Once RIYL's army of robots has calculated the chart values for each artist, they press the "sort by points" button.  Voila.  Power to the people!
