Two of my favorite recent TV theme songs from the past five years: 1) The Mandalorian, by Ludwig Goransson, which is the best Star Wars theme since the Duel of the Fates. 2) Foundation, by Bear McCreary, which is also great. Hans Zimmer's theme for The Crown is also quite good. I actually think a lot of prestige streaming dramas (which expensive-looking credits) have pretty good theme music. Schitt's Creek also had a really great outro theme.
