Vista - Suggestion: Exploring A Music Play list In My Computer

MY REASON: I have in many times needed to do a certain thing to the files in a music play list, for example to copy the files to another place (Now, you should manually see the file locations and copy them one by one!)

My Suggestion: It will be very good if one can explore a music play list in Windows Explorer, just like it is a folder (Explorer should automatically see the file locations and show them in a window, just like it does when searching). This way, one can do any normal job (copying, moving, burning, zipping,...) to the files easily.
