What is "sverigetopplistan"

Sverigetopplistan (lit. "Sweden top list") is the Swedish national record chart, earlier known as Topplistan (1975–1997) and Hitlistan (1998–2007) and known by its current name since October 2007, based on sales data from the Swedish Recording Industry Association (in Swedish Grammofonleverantörernas förening). Before Topplistan, music sales in Sweden were recorded by Kvällstoppen, whose weekly chart was a combined albums and singles list.
