I've never read Finnegans Wake, but it made a lot more sense when I heard it spoken out loud, which I think was the intent. Here's Joyce reading it: https://youtu.be/M8kFqiv8Vww?si=YO69BX_KVEINr5mo.

I had the same sensation when I listened to Fiona Shaw performing The Waste Land by T. S. Eliot, who breathes completely new life into it: https://youtu.be/lPB_17rbNXk?si=IBKeyTnu0KCZ2r_U. (She's an amazing actress, truly one of the greats.) The poem is supposed to many types of voices talking, so you lose a lot of meaning if you just read it like a poem (even T. S. Eliot himself reads it quite poorly!).
