multimedia columns in list view

[yelo_3 <yelo_3 yahoo it>]

Hello, I really think that nautilus list view lacks of columns for
multimedia files:

Artist, Album, Title, Track, ..., Bitrate, Duration,Resolution

adding a column in nautilus source is very simple, but I don't know
which library is the best to be used to inpsect files for metadata and
tags.
Can you help me, so I can submit a patch?
