How? :Save___ and :Load____?

I'm making a :Save___ and :Load___ but I want to save a SoundId, what method would this be used for? I've tried saveing it like this ":SaveString", ":SaveInstance" ":SaveNumber", and I think one other way, this is in a playergui, this is for a game I am currently making, dont judge me on the games I make.

Don't use DataPersistence, it is outdated and very buggy. DataStore is much better
