Play folder or file in iTunes without adding it into library

Is there a way to play a file or folder in iTunes without adding it into iTunes library?

I have quite large collection of music that i want to listen to but not necessarily keep. So i want to be able to listen to some music files in a given folder (be it a complete album or just a collection of various songs) and once i'm done listening and close iTunes i want all the files that i just listened to be gone from iTunes library.

And if it is not possible, maybe there is a workaround to achieve similar results?
