Question: In the late 1960s, the term heavy metal was used interchangeably with hard rock, but gradually began to be used to describe music played with even more volume and intensity. While hard rock maintained a bluesy rock and roll identity, including some swing in the back beat and riffs that tended to outline chord progressions in their hooks, heavy metal's riffs often functioned as stand-alone melodies and had no swing in them. Heavy metal took on "darker" characteristics after Black Sabbath's breakthrough at the beginning of the 1970s. In the 1980s it developed a number of subgenres, often termed extreme metal, some of which were influenced by hardcore punk, and which further differentiated the two styles. Despite this differentiation, hard rock and heavy metal have existed side by side, with bands frequently standing on the boundary of, or crossing between, the genres.
Is there an answer to this question: In heavy metal, riffs typically form what element of a song?

Answer: stand-alone melodies

Question: At the foundation of the Order, the "Medal of the Order of the British Empire" was instituted, to serve as a lower award granting recipients affiliation but not membership. In 1922, this was renamed the "British Empire Medal". It stopped being awarded by the United Kingdom as part of the 1993 reforms to the honours system, but was again awarded beginning in 2012, starting with 293 BEMs awarded for the Queen's Diamond Jubilee. In addition, the BEM is awarded by the Cook Islands and by some other Commonwealth nations. In 2004, a report entitled "A Matter of Honour: Reforming Our Honours System" by a Commons committee recommended to phase out the Order of the British Empire, as its title was "now considered to be unacceptable, being thought to embody values that are no longer shared by many of the country's population".
Is there an answer to this question: What was the medal renamed as?

Answer: British Empire Medal
