this instance, Billboard felt that crediting Britney Spears on the
listing of 'S&M' atop the Hot 100 was the correct course of action
due to the fact that her guest vocal version of 'S&M' outsold
Rihanna's solo version two-to-one (193,000 of the song's 293,000 overall
digital sales, according to Nielsen SoundScan). "Add that radio
stations across the U.S. have played the new mix heavily; both artists
have promoted the mix on Tωitter; and, Rihanna promoted the remix in
interviews, the hoopla surrounding the song was too much to ignore (and
not give Spears credit for on this week's ranking). "The examples
you mention, Richard, differ in nature from 'S&M.' The Lopez/Ja
Rule remix was a wholly different song than her original solo version,
and the Da Brat remixes were never the dominantly-played versions at
radio. "All aspects considered, it's a different musical
landscape today and Billboard has many more tools at our disposal to
break down the success and/or reach of different versions of songs. "We
may reconsider artist listings on a week-to-week basis and adjust
accordingly, based on which version is a given week's top seller. A
similar chart precedent even exists: for past listings of double-sided
singles on the Hot 100, the first-listed titles could flip-flop based on
which was the dominant selling side (based on retail reports)
week-to-week. "The case of 'S&M' isn't the last such a
late-in-the-game guest artist remix that we'll see, either; a remix of
Spears' 'Till the World Ends' - sporting Ke$ha and Nicki Minaj - arrives
next week."
