Insert a dash between artist and title

currently I have:
Joseph Bloggs The River Runs
I would like to have :slight_smile:
Joseph Bloggs - The River Runs

also..

Is there a quick way to reverse:
Joseph Bloggs - The River Runs
to
The River Runs - Joseph Bloggs

If these are in the FAQ I couldn't find them and can you direct me thereto.
Cheers

Where do you want to insert (or remove) the dash?
In the filename? Or in a tag like TITLE?

Do you currently have "Joseph Bloggs" in ARTIST and "The River Runs" in TITLE?
