'In the Heights'. All of it. Incredible musical.

Also, I love 'Diva's Lament' from Spamalot, 'Who Needs to Dream' from Copacabana and pretty much all of Moulin Rouge. I love all of the old classics too, and can never get enough of Anything Goes, Sweeney Todd, Sweet Charity ('Rhythm of Life' was MADE to be sung in Welsh! ) and a whole host of others.

Can't stand Sound of Music. Sorry!
