Ironically enough, I didn't finish this arrangement until my last semester of college, but I still feel like the lyrics and their morose theme of "whelp, I messed up; guess I'll take the L and try again when I get the chance" still apply to me even when I'm not in school.
Play around with the dynamics on this one. Don't be afraid to get so loud that your voice breaks, as long as you also have a quiet moment or two.
