Sales of Neil Diamond's Sweet Caroline are up by 597% a week after the song became a source of comfort following the explosions at the Boston Marathon.
Nielsen SoundScan said the track sold 19,000 copies this week. It sold 2,800 the previous week and 1.75 million to date.
The crowd-pleasing song is a staple of Boston Red Sox games. It makes no specific mention of Boston or the Red Sox, but the team started playing it regularly at Fenway Park more than a decade ago and fans took to it.
The New York Yankees, Toronto Raptors and other professional sports teams have also played the song at games in the days after last week's deadly blasts.
Diamond released Sweet Caroline in 1969. It is addressed to Caroline Kennedy.
