If Tupac Shakur and the Notorious B.I.G. were still alive, Eminem might be nominated for the Nobel Peace Prize for bringing them together. As it is, putting the slain rival rappers on the same track is no small feat. MTV News reports that Tupac and Biggie swap verses on the Eminem-produced song ''Running (Dying to Live),'' which will be the first single from the soundtrack of ''Tupac: Resurrection,'' a documentary about Shakur that's coming out in November.
The song includes rhymes from both rivals (first Biggie, then Tupac) about clashing with the police and coping with adversity. Eminem added piano and strings and sampled the chorus from blues-rocker Edgar Winter's ''Dying to Live'' (sample line: ''Why am I dying to live, if I'm just living to die?''). The song is one of four Eminem-produced cuts on the soundtrack, which drops Nov. 4. ''Tupac: Resurrection,'' which features voiceover narration culled from the late rapper's interviews, opens Nov. 14.
