Thank you for the feedback.
Now, here is something to think about:
If you want to get rid again because the player on your PC is not so ignorant and knows how to sort tracks by different criteria.
For this you have to write an action of the type "Guess values" for TITLE.
You then cut the track number from the title
This is then much easier if you use a separator between the added track number and the original title that is hardly ever used in normal text - I suggest the underscore _
So adapt the tag-tag-converter-mask like this:
$num(%track%,2) _ %title%
And another thing: probably your player now really sorts all titles more or less numerical.
That is ok for a single album. But if you want to have several ones then you would first listen to all the first tracks, then the second ones and so on.
For such a list modify the mask as follows:
$num(%counter%,2) _ %title%
This creates some kind of playlist sequence.
You see that modifying the TITLE field depends on the specific context. I would sugest that you keep the originals in a separate place and then edit the tags only in copies for the smart phone.
