For me it was GoT, I just thought the miniature landscapes looked way too cool. Also I am watching Kimmy Unbreakable which has a theme song that I think is pretty catchy.
I listened to House MD on crappy “watchtvforfree.net” type websites over a decade ago, and I only just realized now that the theme wasn’t supposed to change every episode. I just checked YouTube for the intro and I’m super familiar with all three versions haha
I like them all in their own way, but Teardrop obviously stands out.
