Increase artist/title check for single songs to prevent matches such as the following
"Jimmie Rodgers - Together" is matched to "Jimmie Rodgers - Let's Stay Together"
"Johnny Mathis - Come Back" is matched to "Johnny "Country" Mathis - If You Should Come Back Today"
"Rush - Happy" is matched to "DJ Rush - Snare Happy"
but of course we only want to adjust this slightly cause could prevent some good matches, impossible to get it right for all circumstances
