Corrected, thanks!
Ubuntu comes with mawk by default and the code I provide is for gawk,
could you check if gawk is installed?


OK, try this one, if it doesn't work, tomorrow I'll continue to debug Smilie

Code:
find -iname '*.mp3' -exec bash -c "
  id3 -Rl \"\$@\" | 
    awk -F'\012' '
      \$2 ~ /Title: \*$/{
        print \$1
        }' IGNORECASE=1 RS=   
    " {} +

Notice that the above code checks only for empty Title tag (I'm not checking the other tags right now).

I tested with adding tee after the id3 call and got the output from all mp3 files. So far so good. My guess: it's in the awk part.

And, of course, it will be much easier to write a shell script for that: it will be less efficient, but we could rich the desired functionality sooner Smilie

Yes,
I suppose it's because of the awk version and because of the crazy "escaping" Smilie

Well, this is a learning fase for me. I just want to see if it's possible. It's eyeopening to work with streams. It's powerful and I want to get it. Playing with this helps.

So I played. And discovered this:
Code:
$ find -iname '*.mp3' -exec bash -c "
  id3 -Rl \"\$@\" | 
    awk -F: '
      /Title:/{
        print \$2
        }' IGNORECASE=1 RS=" {} +
 ./alex roeka - 1999  - wildernis/09 - Alex Roeka - Dronken Ochtendkade.mp3
 ./alex roeka - 1999  - wildernis/04 - Alex Roeka - Help me, ik ben echt.mp3
 ./alex roeka - 1999  - wildernis/06 - Alex Roeka - Noem het geen liefde.mp3
 ./alex roeka - 1999  - wildernis/02 - Alex Roeka - Schotwond in m'n ziel.mp3
 ./alex roeka - 1999  - wildernis/03 - Alex Roeka - Blues bij de deur waar de man staat.mp3
 ./alex roeka - 1999  - wildernis/10 - Alex Roeka - De lange liefde lang.mp3
 ./alex roeka - 1999  - wildernis/11 - Alex Roeka - Steeds dichter bij de grond.mp3
 ./alex roeka - 1999  - wildernis/12 - Alex Roeka - Vader.mp3
 ./alex roeka - 1999  - wildernis/08 - Alex Roeka - De mannenwoestijn.mp3
 ./alex roeka - 1999  - wildernis/07 - Alex Roeka - Kermis in ravenstein.mp3
 ./alex roeka - 1999  - wildernis/01 - Alex Roeka - Het schip genaamd 'de Nacht'.mp3

No track 05! But it is there. Look.
Code:
$ find -iname '*.mp3' 
./alex roeka - 1999  - wildernis/05 - Alex Roeka - Laat je maar zinken.mp3
./alex roeka - 1999  - wildernis/09 - Alex Roeka - Dronken Ochtendkade.mp3
./alex roeka - 1999  - wildernis/04 - Alex Roeka - Help me, ik ben echt.mp3
./alex roeka - 1999  - wildernis/06 - Alex Roeka - Noem het geen liefde.mp3
./alex roeka - 1999  - wildernis/02 - Alex Roeka - Schotwond in m'n ziel.mp3
./alex roeka - 1999  - wildernis/03 - Alex Roeka - Blues bij de deur waar de man staat.mp3
./alex roeka - 1999  - wildernis/10 - Alex Roeka - De lange liefde lang.mp3
./alex roeka - 1999  - wildernis/11 - Alex Roeka - Steeds dichter bij de grond.mp3
./alex roeka - 1999  - wildernis/12 - Alex Roeka - Vader.mp3
./alex roeka - 1999  - wildernis/08 - Alex Roeka - De mannenwoestijn.mp3
./alex roeka - 1999  - wildernis/07 - Alex Roeka - Kermis in ravenstein.mp3
./alex roeka - 1999  - wildernis/01 - Alex Roeka - Het schip genaamd 'de Nacht'.mp3

Why is that? I did:
Code:
$ id3 -Rl alex\ roeka\ -\ 1999\ \ -\ wildernis/05\ -\ Alex\ Roeka\ -\ Laat\ je\ maar\ zinken.mp3 

Filename: alex roeka - 1999  - wildernis/05 - Alex Roeka - Laat je maar zinken.mp3
Title: Laat Je Maar Zinken           
Artist: Alex Roeka                    
Album: Wildernis                     
Year:     
Genre: Other (12)
Track: 5
Comment: Het~Nachtdier

So why is it missing in the first list? Strange.

OK,
one problem at a time.
This should work with GNU awk (gawk) for mp3 files:

Code:
find -iname '*.mp3' -exec id3 -Rl {} + |
  awk -F: '/filename: / {
    if (f) print fn
    fn = $2; f = x
    }
   /^(title|a(rtist|lbum)): *(|unknown|track) *$/ {
      f++
      }
    END {  
      if (f) print fn
      }' IGNORECASE=1

With mawk (the default awk on Ubuntu), you'll need something like this:
Code:
find -iname '*.mp3' -exec id3 -Rl {} + |
  mawk -F: '/Filename: / {
    if (f) print fn
    fn = $2; f = x
    }
    /^(Title|A(rtist|lbum)): *(([Uu]nknown|[Tt]rack *)| *)$/ {
      f++
      }
    END {  
      if (f) print fn
      }'

Oh.. I've gawk installed. I even get the gawk manpage if I do 'man awk' Smilie

      }
    END {  
      if (f) print fn
      }'

I find track 01 and 07. Both have empty titles.
The tracks that should be found are track 02 (which is titled 'track 01', yes I really messed this one up) and track 03 (which is titled 'unknown')

To be sure: gawk is my default awk.

$ awk -W version

Yes,
awk is GNU awk now.
Try this for track ...:

Code:
find -iname '*.mp3' -exec id3 -Rl {} + |
  awk -F: '/filename: / {
    if (f) print fn
    fn = $2; f = x
    }
    /^(title|a(rtist|lbum)): *(|unknown|track.*) *$/ {
      f++
      }
    END {  
      if (f) print fn
      }' IGNORECASE=1

Sorry for the multi-correction Smilie
The GNU awk version should include always IGNORECASE=1 in order to ignore the case.
