question: Which magazine changed its practice of counting sales and airplay separately?
context: Although its commercial impact was lessened by the ongoing success of the parent album, "Something" / "Come Together" was certified Gold by the Recording Industry Association of America (RIAA) on 27 October. During the single's chart run on Billboard in the US, "Something" peaked at number 3 until the magazine changed its practice of counting sales and airplay separately for each song; following this change on 29 November, the single topped the Billboard Hot 100, for one week. "Come Together" / "Something" became the Beatles' eighteenth number 1 single in Billboard, surpassing Elvis Presley's record of seventeen. In the other US national charts, Record World listed "Something" / "Come Together" at number 1 for two weeks and "Come Together" / "Something" for the remaining three weeks at number 1, while in Cash Box magazine, which continued to rank each song separately, "Something" peaked at number 2 and "Come Together" spent three weeks at number 1.As the preferred side, "Something" was number 1 in Canada (for five weeks), Australia (five weeks), West Germany (two weeks), New Zealand and Singapore. The combined sides reached number 4 in Britain. There, the release was highly unusual, given the traditional preference for non-album singles. In addition, according to former Mojo editor Paul Du Noyer, "so enormous were sales of Abbey Road that demand for the single was inevitably dampened."On 17 February 1999, "Something" was certified double Platinum by the RIAA. In its 2014 list titled "The Beatles' 50 Biggest Billboard Hits", Billboard places the double A-side single in sixth place, immediately after "Let It Be" and ahead of "Hello, Goodbye". Additionally, "Something" is placed again at number 30, representing the song's performance before the November 1969 Hot 100 rule change.
