PPL has announced that Pink is the most-played female artist of the 21st century (so far) within this United Kingdom of Great Britain and Northern Ireland, beating Madonna, Katy Perry, Rihanna and Lady Gaga to the top spot.We know this because of a new PPL airplay chart that has just been published, the first in a series being launched by the UK record industry’s collecting society in the run up to this year’s National Album Day on 16 Oct.
