Dynamically create variables of a object

I am taking a json file and reorganizing it as a object in a new format (Not the same formatting as the json file I am reading, as I want to group variables differently) so I can use it. This requires creating a lot of variables with names that are unknown in advance.

I can dynamically create a new variable in my project like this:

object[variablename]

However, I would like to be able to do things like this

library[musicLibrary.Key].name = musicLibrary.alblum;

and

library[musicLibrary.Key].songs.[musicLibrary.title].name = musicLibrary.song;

Is there any way I can possibly do this?

My current looping code for the json looks like this:

var library = {}; 

for(var i = 0; i < musicList.songs.length; i++) {
//read json and reorganise it into a object
}

for(var i = 0; i < musicList.songs.length; i++) {
    var key = musicLibrary.Key;
    library[key] = library[key] || {};
    library[key]['name'] = musicLibrary.alblum;
    library[key]['songs'] = library[key]['songs'] || {};
    library[key]['songs'][musicLibrary.title] = library[key]['songs'][musicLibrary.title]  || {};
    library[key]['songs'][musicLibrary.title]['name'] = musicLibrary.song;
}
