DUFFY’S hit single Mercy came fourth in a list of the most played songs of 2009.

The Nefyn songstress is one of several solo female singers in the top 10.

Music rights group PRS for Music compiled the top 100 tracks that received the most air play during the year, which was topped by Gabriella Cilmi’s Sweet About Me.

Other pop divas in the top 10 were Jordin Sparks with No Air and Jennifer Hudson, who sang Spotlight.

Take That, Rihanna and the Sugababes were the most popular acts, each getting four entries.

The top 100 was compiled using the number of plays and performances online, live, and on television and radio.
