Wrong tags and wrong name

[iliast]

I have song title in Artist tag field and the artist in Title tag field.
How can I fix that?
p.e. the name (and tags) is now "War Machine - Kiss". I want to have "Kiss - War Machine"
Thank you.

Actions and batch-operations

How to swap the contents of 2 tag fields? Example how to swap TITLE and ARTIST: Create a new action in an existing action group or make a new action group. Action type: Guess values Source format: %title%~%artist% Guessing pattern: %artist%~%title% Note: The ~ sign is just used to separate the two fields, you could take any other sign that does not appear in your fields, e.g. ¢ or an extended unicode character like ∞ or ∑.
