I am also no super fan but like quite a lot by him. I have no real order but EDWARD SCISSORHANDS, NIGHTMARE BEFORE CHRISTMANS (also love the movie), MIDNIGHT RUN and BEETLEJUICE are on the list. And a bunch of his TV themes like SIMPSONS, THE FLASH and TALES FROM THE CRYPT maybe. Probably also BATMAN as I think that was the score I got aware of him.
His newer output in scores often leaves me rather cold. But the concert I know so far works are indeed great.
