The best-selling singles of all time are heavy on pop, but not a whole lot outside of that. Rock, country, and rap are scattered throughout, but are largely missing from the top 25.
Among the RIAA's (Recording Industry Association of America) biggest singles ever, Eminem and Katy Perry are the most popular artists, with three songs each in the top 25. Ed Sheeran, though, claimed the top spot with "Thinking Out Loud."
We put together RIAA's data on the 25 best-selling singles of all time, which is based on certified units sold in the US.
