Audio and Mic Malfunction: According to reports, the sound at the 2020 Oscars was faulty, with low mic volume and inaudible backing tracks, forcing Eminem to scream or shout his lyrics to be heard.
High-Energy Live Performance: Performing "Lose Yourself" live involves rapid, aggressive rapping while moving around on stage, which is far more physically draining than recording in a studio.
Live vs. Studio Recording: While studio tracks like "Godzilla" are flawlessly edited for speed and breath control, live performances, especially surprise ones, rarely allow for the same precision.
