mp3 tag on top of folder?

Hi people,

got an important question (for me) ;-):

I have i huge mp3 collection with lots of different genres in it.

So it would be nice if there would be on top of every folder/album for example an info with size/genre etc.
i´ve seen it sometimes in folders i´ve downloaded.

example: [ 4 of 4 files = 100% complete of 23.8MB | Rock&Roll 2007]

Is it possible to generate such an information for every folder with Mp3Tag or another nice little program?

Thanks a lot for your support!
