2- Start by the (Man in the mirror) it's u to change and don't tell me (Leave me alone).
3- (You r not alone) (Hold my hand) as (I wanna b startin somethin) at (2000 Watts) so let's help the helpless.
4- (Remember the time) that we will b judged on 4 all our deeds so work hard for it.
5- (Don't walk away) when u see somethin going wrong and u can help in it.
