self containing audio library file

[typ911411and718]

is there a way to create a library file that contains all the songs or video files of your choosing? for instance, i want to make a playlist, but i don't want the playlist to be a shortcut to those files, instead, i want the playlist to house its own copy of those files. if [reader] knows about icon {elemental} libraries and how one icon library file is, in itself, a collection of, what used to be, individual icons, then [reader] should understand what i'm referring to.

(...don't question my query, it makes some sense, in some way, to me to do this...)

please help. thank you.
