Is there a way to search the DB and query which tracks don't have replay gain? I have the Extended Search plugin, and tried a boolean for %__replaygain_track_gain% and came up with a bunch of positives, but I want to reverse that. I don't know enough about queries to figure it out on my own.

<field> MISSING" - Returns only items with the <field> missing (or empty).

Or something like this:

__replaygain_track_gain MISSING


EDIT: Using Extended Playlist Generator

If you use columnsUI you could put all your stuff into one playlist, add a column and sort by %__replaygain_album_gain% / %__replaygain_track_gain%

I got a column UI script here:

that you can download here:

if there are replaygain info, into the RG colum, there is not any pink dot
if replaygain info are missing, there are one or two pink dots (one dot=track or album gain missing, two means both are missing), I think it is quite useful.

I'm still confused. Do I use a boolean search? Where does the word missing go? I tried and it returned all my tracks again.

edit: I knew I could do a sort in columns ui, but I was hoping to find a way to do it with the Search so I wouldn't have to muck about chaning FCS's and such.

To reverse in the extended search, just do:
$if(%__replaygain_track_gain%,,1) as Format, type boolean

Works. Thanks.
