Problem: Background: The Sweet (also known as Sweet) is a British glam rock band that rose to worldwide fame in the 1970s. Their best known line-up consisted of lead vocalist Brian Connolly, bass player Steve Priest, guitarist Andy Scott, and drummer Mick Tucker. The group was originally called Sweetshop. The band was formed in London in 1968 and achieved their first hit, "Funny Funny", in 1971 after teaming up with songwriters Nicky Chinn and Mike Chapman and record producer Phil Wainman.
Context: Guitarist Mick Stewart joined in 1969. Stewart had some rock pedigree, having previously worked with The (Ealing) Redcaps and Simon Scott & The All-Nite Workers in the mid-1960s. In late 1965, that band became The Phil Wainman Set when the future Sweet producer joined on drums and the group cut some singles with Errol Dixon. In early 1966, Stewart left and later worked with Johnny Kidd & The Pirates.  The Sweet signed a new record contract with EMI's Parlophone label. Three bubblegum pop singles were released: "Lollipop Man" (September 1969), "All You'll Ever Get from Me" (January 1970), and a cover version of the Archies' "Get on the Line" (June 1970), all of which failed to chart. Stewart then quit, and was not replaced for some time. Connolly and Tucker had a chance meeting with Wainman, who was now producing, and knew of two aspiring songwriters, Nicky Chinn and Mike Chapman, who were looking for a group to sing over some demos they had written together. Connolly, Priest and Tucker provided the vocals on a track called "Funny Funny" which featured Pip Williams on guitar, John Roberts on bass and Wainman on drums. The latter began offering the track to various recording companies. The band held auditions for a replacement guitarist and settled on Welsh-born Andy Scott. He had most recently been playing with Mike McCartney (brother of Paul) in the Scaffold. As a member of the Elastic Band, he had played guitar on two singles for Decca, "Think of You Baby" and "Do Unto Others". He also appeared on the band's lone album release, Expansions on Life, and on some recordings by the Scaffold. The band rehearsed for a number of weeks before Scott made his live debut with Sweet on 26 September 1970 at the Windsor Ballroom in Redcar.  The Sweet initially attempted to combine various musical influences, including the Monkees and 1960s bubblegum pop groups such as the Archies, with more heavy rock-oriented groups such as the Who. The Sweet adopted the rich vocal harmony style of the Hollies, with distorted guitars and a heavy rhythm section. This fusion of pop and hard rock would remain a central trademark of Sweet's music and prefigured the glam metal of a few years later.  The Sweet's initial album appearance was on the budget label Music for Pleasure as part of a compilation called Gimme Dat Ding, released in December 1970. The Sweet had one side of the record; the Pipkins (whose sole hit, "Gimme Dat Ding", gave the LP its name) had the other. The Sweet side consisted of the A- and B-sides of the band's three Parlophone singles. Andy Scott appears in the album cover shot, even though he did not play on any of the recordings.
Question: Did this mix up work for them?
Answer: This fusion of pop and hard rock would remain a central trademark of Sweet's music and prefigured the glam metal of a few years later.

Background: Kara (Hangul: kara, Japanese: kara, often stylized as KARA) was a South Korean pop girl group formed by DSP Media in 2007. The group's final lineup was composed of Park Gyuri, Han Seungyeon, Goo Hara and Heo Youngji. Members Nicole Jung and Kang Ji-young officially departed from the group in 2014, while Kim Sung-hee left in 2008. The group's name comes from the Greek word "chara" (khara, lit. "joy"), which they interpreted to mean "sweet melody".
Context: At the end of January 2009, DSP announced that it would commence voting on January 28 at the group's official website for the follow-up single to "Pretty Girl", which ended on February 2. By the deadline of February 2, "Honey" was the clear winner, with 60% of the votes. The song was remixed from the original version, and also underwent a slight name change from "hani" (Ha-ni) to "Honey". The group released the music video for "Honey" on February 16 and had their first live broadcasting comeback on KBS's Music Bank program on February 13, 2009; a repackaged mini-album entitled Honey followed on February 19 which featured remixed versions of songs from the group's previous EP. "Honey" became the group's first number one single when it topped Gaon's weekly singles chart. The song earned the group their first music show award on M! Countdown on March 5. It held onto the position for three nonconsecutive weeks. The song also won the Mutizen award on SBS's program Inkigayo and the "Best Dance Award" at the 2009 Mnet Asian Music Awards.  At the end of March, the group was chosen for the fourth season of MBC's Idol Show, which marked the group's first hosting duties for a show. The group then had a reality show called MTV Meta Friends, which chronicled a group of fans getting a chance to become friends with the group members. For the show, the group had their first concert since their debut in 2007.  In June 2009, the group stated they would make their comeback in late July, with their concept upgraded. The first teaser pictures of the group were then released in mid-July, showing radical changes in the group's style and also saw a slight return of their "strong and mature" image previously seen from their debut. Their single "Wanna" was released on July 28, 2009 and immediately charted on various digital music charts. The music video was released on July 29, with the full album, Revolution, available online on July 30. Comeback activities commenced on July 31, beginning with KBS's Music Bank; the group performed both "Wanna" and "Mister". "Mister" proved to be popular with netizens due to the "butt dance" that is featured prominently in the choreography. Due to the popularity of "Mister", Kara's overall popularity increased, evidenced by an influx of advertisement requests by various companies; in total, they had more advertisements in October 2009 than they had had the previous two years. "Wanna" also became a number one single for the group and won the Mutizen award on August 30, 2009 from Inkigayo. During promotions for Revolution, the group also performed internationally, including at Bangkok's Parc Paragon.  On November 25, 2009, M.Net premiered the reality show called Kara Bakery, which followed the group as they attempted to plan, open, and advertise their own bakery. The show had 8 episodes and ran until early 2010. All proceeds from the bakery was donated to charity.  On December 14, 2009, it was reported that the group held a fan-meeting for their Japanese fans earlier that year on February marking the group's first promotional tour in Japan. Over 3,000 fans were reportedly registered, exceeding the capacity of the venue which resulted in a second showcase.
