I find ballet as a medium a bit tedious. I admire the skill, but have no interest in watching it.
Ballet music, though, is some of my favourite music. Especially the 20th century ballets, Prokofiev and so on. Putting the formalism of classical music structure to dance rhythms just really works. (Ok, I know that non-ballet classical music was often based on dances too, but modern ballet rhythms take it to a new level.)
