Please test your expressions in MP3tag with Convert\>Tag-Tag and the scripting function $regexp()

To replace everything leading in parenthesis, try Convert\>Tag-Tag for TITLE:  
Format string: `$regexp(%title%,^\(.*?\)\s*,)`

In general, to address the captured string part, use $1 instead of \1

... and there are a lot of threads that deal with the removal of parenthesis and their contents, e.g.

> I found this Action: It works but it leaves a space in the title. It's not that big a deal when the parenthesis are at the end, but it's an issue when they're at the beginning. "(I Just) Died in Your Arms" becomes " Died in Your Arms". Can the parenthesis be removed along with the extra space? Edit: Here's what that linked Action is doing so you don't have to download it to see: Regular expression: \(.+\)
