Any 1.20 sounds can be played with the /playsound command in vanilla 1.19.3 without the update_1_20 data pack enabled

You can use the /playsound command to play any sound from the 1.20 experimental datapack, without having it enabled. Just open any 1.19.3 world with cheats enabled and use the /playsound command for any camel, hanging sign, chiseled bookshelf, or bamboo block sound.
