Indeed, my initial idea of "signature song" was something broader than a personal favorite (although the two can easily go together). More perhaps like a song that everyone assicates with U2. Similar as Queen and Bohemian Rhapsody, or Led Zeppelin and Stairway To Heaven.
But reading all the comments and posts here, I now come to think that for U2 there are a lot of variations when it comes to signature song.
It seems to depend on age as well as geographical location. And none seems to be less than another.
Fascinating
