Closing the week of February 25, 1995, Biggie's single "Big Poppa/Warning"—released on December 5, 1994—had spent six weeks total, and five weeks at #1, on "Billboard"'s Hot Rap Singles chart. On the pop singles chart, the Billboard Hot 100, amid 24 weeks total, it peaked at #6 on March 18. Yet on February 21, Bad Boy released another "Big Poppa/Warning" single version whose B side closed with "Who Shot Ya?" Although not on his album, it could sound familiar via "K. Murray Interlude," a brief track on Mary J. Blige's second album, "My Life". Both share a looping sample from soul singer David Porter's song "The Masquerade is Over," by now sampled in many rap songs. Especially popular among them is "Who Shot Ya?"—among rap's most influential and historic songs. Its republished lyrics may omit Puffy's vocals, which precede Biggie's and recur.
