Random but is there anyway to count the number or tags / fields any given track has. Just curious. In my case I'd just like to know if I could use that metric to immediately tell which tracks may be missing some tags I'd normally add & which tracks are data rich. Some files I have contain a heap of extra but informative tags

One possible solution is creating a string of all tag fields using `$list()` with a specific field prefix (here: the 3-character long `===`) and the same strings without the prefix.

The character difference can tell the number of fields:

`$div($sub($len($list(===,,)),$len($list(,,))),3)`

With the above calculation you could [add a new column](https://docs.mp3tag.de/customization/file-list/) in your [File List](https://docs.mp3tag.de/getting-started/main-window/#file-list) like this:

Then you can sort your tracks in ascending or descending order by this column to see which one deviates.

For those interested in the calculation:

If the command `$list(===,,)` would show  
_===GENRERock===YEAR2025===Barcode6d6574616c677572752e6d65===TITLEBlack Mamba===ALBUMThe Revenge of Alice Cooper===TRACK01===ARTISTAlice Cooper_

then `$len` (length of the string) would show **142**

If the command `$list(,,)` - without additional prefix characters - would show  
_GENRERockYEAR2025Barcode6d6574616c677572752e6d65TITLEBlack MambaALBUMThe Revenge of Alice CooperTRACK01ARTISTAlice Cooper_

then `$len` would show **121**

`$sub(142,121)` - subtraction - would show **21**

`$div(21,3)` - division - would show **7**

The number 3 in this $div command is the number of choosen prefix characters.  
=== are 3 characters long.

@Florian @LyricsLover MANY THANKS! This is super cool…now I'm off to play with my new toy.
