Re the media-columns extension, I also discovered that if it's installed it makes Nemo extraordinarily slow at loading folders with a large number of files in them - it took over two minutes for one folder that otherwise loads in a second or two - even if the columns were not configured to show!
So I had to uninstall it as it made Nemo unusable. So an audio tab would be very useful.
