</div>

maybe my idea is a bit overloaded?!

but is there a chances to include parts of different tagfields while using "replace with reg. expressions"?

for example i want to change the title-field "3rd Eye (Atomic Pulse Remix)"

to "3rd Eye feat. ORIGARTIST (Atomic Pulse Remix)"

my expression looks like ^(._)\s((._))$ so i get 2 parts

$1 = "3rd eye" and 2$ = "(Atomic Pulse Remix)"

the with-string should have the information from %ORIGARTIST%

is it possible in any way?

regards mp3tag

please, may i use a variable like %ORIGARTIST% in the 'Replace matches with' field  
while using Action (quick) 'Replace with regular expressions'?

from: ^(._)\s((._))$

with: $1 %ORIGARTIST% $2

don't work here.

If you need a working solution for your request, ...  
then apply one formatstring from the proposals from post#2 above.
