I'm a musical junkie, as you can probably tell from the avatar.
Favorites, roughly in order. With lyrics, totally intending to get earworms stuck in your head:
Phantom of the Opera (night time sharpens, heightens each sensation, darkness stirs and wakes imagination)
Les Miserables (do you hear the people sing, singing the songs of angry men)
Beauty & the Beast (no beauty could move me, no goodness improve me, no power on earth, if I can't love her)
Heathers: The Musical (we can start and finish wars, we're what killed the dinosaurs)
Rocky Horror Picture Show (how d'you do? I... see you've met my... faithful... handyman)
Wicked (loathing! un-adult-erated loathing)
Sweeney Todd (but first sir I think a shave... the closest I ever gave)
The Lion King (I know that your powers of retention are as wet as a warthog's backside...)
Hunchback of Notre Dame (it's not my fault, MEA CULPA, I'm not to blame, MEA CULPA)
Repo! The Genetic Opera (sex murder monster)
Frozen (the snow glows white on the mountain tonight, not a footprint to be seen)
Little Shop of Horrors (I am your deeeeentist... and I get off on the pain I inflict!)
American Idiot (I'm the son of rage and love, the Jesus of Suburbia)
Dr. Horrible's Sing-Along Blog (did you notice that he threw you in the garbage?!)

Don't believe the gender tag. I was born intersex and identify as queer, girl-leaning. So while I can sometimes present as an effeminate guy, that's less than half the time and if anything I'd prefer it say "female" of the two choices offered. I can't change it though, it's bugged.
