Hi
i´ve posted a topic once before, but theres no response. so if i ask the question diffrently, it maybe easier to understand what i mean 🙂
(sorry bad eng)
this is my sad problem. i have a bunch of mp3´s with the album year tagged i front of the album name like this:
(album tag)
"1990 album name here"
i have tried in many ways and searched this forum for a solution, but i cant find a way to change the first space into " - " whitout changing ALL the spaces in the tag... i want it to look like this:
(album tag)
"1990 - album name here"
can someone please help me, this is a tricky thing for a newbie.
i think this must be done in regxp
ps, mp3tag is the most perfect tag prog i have seen, respect and hat off to developers.

Hi, and first of all, you could have edited your original post, not opening a whole new topic. You just posted that one a few hours ago, don't expect immediate answers.
As for your problem, write this short RegExp, it will determine if there are 4 digits at the beginning of the album tag and replaces it with what you need.
Field: ALBUM
Regular expression: (\d{4})\s+?
Replace with: $1 -
It should work (with multiple spaces too)

There are numerous entries in the "regular expressions" section of the forum.
I think the following might work (try with a single track first)
Create an action (Alt-5, new)
Add the action "Replace with regular expression".
Select Album as field
Enter as regular expression "([0-9]+)\s"
(this searches for any digit plus a white space)
Enter for "Replace hits with":
"$1 - $2"
I hope it works.
