Due to heavy rotation on various commercials and trailers , the song became a sleeper hit , peaking at number three on the US Billboard Hot 100 chart and becoming the band 's first top 10 single as well as being the third best selling song in that country . It has since been certified ten times platinum in the USA , making it the one of the best selling singles of all time .
