Bitrate category when searching audio

[MissStabby]

I'm looking to get rid of old "low bitrate" music that i have on my pc.
Though at the moment the best indicator of bitrate i have is filesize, this doesnt work very well though as a long low bitrate track would have a similar size to a high bitrate short track.

It would be really handy to have "bitrate" as a sortable/searchable category for audiofiles.
See the windows example in the attachment:

In Everything 1.5 Alpha, you can add a "Property", 'Audio Bit Rate'.
