 By default all the .m4a files will be stored into the folder named "~/Music/" (will be created if it doesn't exist). You can change the folder name by passing a second argument to the command line as shown in the second example above. DO NOT FORGET the endind '/' on the folder name, or else it will be treated as a filename prefix instead of a folder path.
