Most everything, except impossibly loud rock, including opera
esp. Mozart, and of his, especially Don Giovanni, as well as parts of Il Trovatore, and Don Carlo the first and second act choruses, and the first act trio of Fidelio, for shear bombast, In Questa Regia and for some bel canto lines, Bellini. The arias of Handel's Julius Caesar are also magnificent.
Then there are the Bach Cantatas, especially, "Weinen Traenen ____ Sorgen," and "Jesu der du Meine Seele," The B minor mass, Oh all sorts of other Bach.
I love the Schubert song cycles. Schumann's Dichterliebe is ethereal, surprisingly, it is the piano "accompaniment" that sometimes is most beautiful. When singing, I have sometimes had to stop for crying at something that's happened in the piano.
Lead Belly, Woody Guthrie, many of the unknowns on the Lomax recordings.
