If you DJ and you're at least decent, Get a vinyl instrumental of something simple that's close to the same tempo. Play the accapella and pitch the record/instrumental by hand with it. Record it. This will give u the ballpark. If you're in protools, use elastic audio to fix/fine tune the instrumental till it's perfect with the vocals, then extract the tempo.
When material gain becomes the god before which all must be sacrificed, even one's own humanity, all manner of crimes and pursuant justifications become possible. And when crimes become heinous enough, as in wars of aggression, genocide and enslavement, the perpetrators have little choice but to dehumanize their victims.--Dr. Joy Degruy Leary
