during my last year of high school im planning to rap lose yourself (By Eminem) in front of 1,300 people. Ok, you clicked on this probably thinking goddamn that takes balls, well i guess you're right, to a extent. I was gonna rap the song with a beat in the back but then when i try to rap the song to the beat, the words wont come out (ironic because its lyrics in the fucking song LUL) so i've been thinking of just putting headphones on and rapping it with a beat in the back. Would that be normal or would that look weird? or should i just have the music play in the background on stage with eminem rapping it. Also, i barely speak in school and maybe only 100 or so people know i stutter, maybe less. about 200 probably know me. Wish me luck <3 and comment which way i should do the song if you care.
