Okay, I missed the necro action on this one when I was pouting at the beginning of the year, so I'll repeat the crime. First of all, Jenny, no musicals?! You're dead to me.

Listing a bunch of popular Broadway stuff, for common language.
I find most older musicals pretty intolerable to watch, and when I thought that's what all musicals were, I thought I hated them too, then college came and I roomed with a lot of musical theatre peeps, which opened my eyes (in a lot of ways).
Stagehanded a production of Sweeney Todd in college, so Sondheim is a nostalgic favorite of mine in general.
Les Miserables, always wanted to sing like Eponine, but unfortunately had a voice suited for the innkeeper, at best.
Rent is dated now, but I loved it at the time (I got to see it in it's La Jolla Playhouse days with Neil Patrick Harris *swoon*), and my wife and I would break out in random singalongs to "La Vie Boheme", when we weren't singing "We Both Reached for the Gun" from Chicago. God, I so wanted to be CZJ as Velma Kelly from the movie version.
Wicked was fun, especially for my wife, the nutty Oz fan.
I thought I would hate it, since everyone was going on about it, but saw Hamilton on Broadway and definitely an all time favorite... still can sing every word.
Also found the Book of Mormon pretty charming. I can find a lot of reasons any given day to sing "Hasa Diga Eebowai".
