"Who Shot Ya" or often "Who Shot Ya?" is a song by Brooklyn, New York, rapper the Notorious B.I.G., also called Biggie Smalls, backed by Sean Combs as the "hype man". Puffy's emerging record label, Bad Boy Entertainment, released it on February 21, 1995, on an alternate reissue of Biggie's single "Big Poppa/Warning," out since December 5, 1994. While this 1994 release climbed the Billboard Hot 100, its new B side "Who Shot Ya"—now Biggie's "most infamous classic," with an instrumental now iconic—revised some vocals of a "Who Shot Ya" track, rapped by Biggie and Keith Murray, already issued on a mixtape from a Harlem DJ earlier in 1995.<ref name=":4222222">Bandini, "DJ SNS liberates the original mixtape version of Biggie's 'Who Shot Ya' with a Keith Murray verse (audio)", AmbrosiaForHeads.com, 17 Mar 2014, embeds a YouTube video of a still image plus audio, and wholly addresses the topic: "One particular standout from Stan Ipcus's stellar feature is the bit on 'Who Shot Ya?.' The controversial song, produced by Nashiem Myrick & Diddy (who chillingly flipped a sample by Isaac Hayes' production partner David Porter), featured some uncharacteristic ad-lib shots from Puff Daddy at the time, and seemed to chide 2Pac into the beef that would transpire less than a year later. Like so many great myths surrounding The Notorious B.I.G. and mid-'90s Bad Boy, SNS maintains that his version, hitting the streets first in 1995, featured Keith Murray. While the Def Squad MC's lyrics would later be re-purposed to a Mary J. Blige interlude, with the interview, SNS digitized this moment in time. K.M., like Biggie, is an amazing lyricist who's never been too far from controversy. Here's what he said: 'I had 'Who Shot Ya' with Keith Murray's verse. To this day, no one still has that record. [Laughs.] You only heard Keith Murray's verse on the Mary [J. Blige My Life interlude]. But his whole verse wasn't on there, [it was just a snippet that faded in and out]. I had the full version.'''
