### How to remove/trim leading track numbers?

Action type: Replace with regular expressions  
Regular expression: **`^\s*\d+\s*-\s*`**  
Replace matches with:

This regular expression removes the track number from `01 - Anything..` so that only `Anything...` remains.  
**`^`** matches the beginning of the string. Then any numbers of whitespaces **`\s*`** followed by numbers from 0-9.  
The **`\s*-\s*`** part removes the hyphen and any whitespace characters around it.
