De Burgh has a noted interest in war history, especially that of the First and Second World Wars. His songs contain numerous references to soldiers and battle, and in 2006 he purchased a rare First World War letter written by an unknown soldier.
AllMusic critic Greg Prato has stated: "Depending on who you ask, Chris de Burgh either specializes in pretentious, bombastic art rock disguised as pop or is a master of penning soaring and majestic compositions." The BBC has said of de Burgh: "To his millions of fans, Chris de Burgh is the ultimate romantic singer. But to many others he's a figure of fun." When the staff of Melody Maker were putting together a lampoon edition of a new arts and music magazine, they chose de Burgh for the cover. His signature song, "The Lady in Red", has been repeatedly voted one of the public's most disliked songs. In 2006, Neil Norman, writing for The Independent, described de Burgh as "the world's naffest balladeer". In his favour, Mike DeGagne, writing for AllMusic, has acclaimed de Burgh as "a genuine master of the soft ballad" and "one of the finest mood-invoking artists ever".
