I need to create a new Expression field, where I can specify for a list of songs an incremental number (1, 2, 3,... n). I need this so that I can recognize (by their number) these songs when I find them in other playlists.

Expr. 1        Song
1                 a
2                 b
3                 c
.                  .
.                  .
.                  .
n                 n

Is this possible?

Thank you

Here are some ideas, not knowing exactly how the number will be used.

   - In a smartlist/playlist, you will automatically get a Seq # column.  This is read-only.
   - You can use Fill Track Numbers from List Order.
   - You can use the Counter() function to assign a monotonically increasing sequence of integers to fields - edit the field(s), and use =Counter().  Counter() will not work as you expect as an expression column.
   - In the Rename, Move and Copy dialog, you can use CustomData(#) to get sequence numbers.

And now there is a new option.  I just created a pscriptor Numberize scriplet (attached):

# Returns a sequence of numbers defined by the arguments passed via -a.  A starting number
# and possible increment can be supplied (both default to 1).  The counter restarts at the
# beginning of each group, if defined.  The format of the -a argument is as follows:
#
#   -a "seq=<start number>+<increment> field=<grouping field name>"
#
# where <start number> is the starting number of the sequence, +<increment> is the increment
# to be added to the previous value (the +<increment> is optional, and defaults to 1).  The
# <grouping field name> defines the grouping of files, where withing each group, the sequence
# of numbers restarts at the <start number>. If the field=<grouping field name> is absent,
# the grouping will be the entire selection.

Thank you Mr C, the last option was what I needed , and it worked great again!

Numberize is now included in pscriptor 1.10.
