Launched in January 2014, the IFPI Global Artist Chart was the first global chart to accurately capture the popularity of artists across streaming channels, alongside digital and physical album and singles sales. The independently verified chart includes sales of albums across digital, CD and vinyl formats; singles, both downloaded and physical; and streams across the calendar year. The chart includes all the music of each artist featured, not just one track or album. It uses album equivalent units to combine measurements of downloads, physical sales and streams.
