WICKED-
'Defying Gravity', when Elphie says, "It's ME!" and she starts to 'fly' and everything- it's beautiful because it's such a turning point in her story.
'Finale', when Glinda and Elphaba sing, "Who can say if I've been changed for the better- because I knew you, I have been changed..." and are cut off by the angry mob shrieking about wickedness, etc, again...
RENT-
'Goodbye, Love'- it is the perfect, 'Ohmigod, I'm brokenhearted and crying and yet I can still belt somehow' song. Though, I think that it's really only good when you're there live to see it.
'I'll Cover You, Reprise' is everything that a mourning song should be. Pain and love intermingle into a bittersweet plea that oozes from every line... It sounds like heartbreak, tragedy, and emptiness. It's amazing :)
PHANTOM OF THE OPERA-
*The very beginning, at the end of the auction, when the chandelier rises and the theme begins to play*
'Music of the Night', is... indescribable. Time stops when a decent voice sings this song.
LES MISERABLES-
'Do You Hear The People Sing', simply makes your heart sort of pound. My friend told me about what happens in the end of Les Miz, so the shock factor of it was spoiled for me, but... wow!
A CHORUS LINE-
*Paul's monologue*
'What I Did For Love' made me want to cry. The voices were so clean and pure and sure of everything they were saying- I don't know, but it felt so... innocent.

I know that I'll have more later but these are just off of the top of my head
Grown-ups never understand anything for themselves, and it is tiresome for children to be always and forever explaining things to them.
