Background: The Kooks are an English pop rock band formed in 2004 in Brighton. The band currently consists of Luke Pritchard (vocals/rhythm guitar), Hugh Harris (lead guitar/synth), Alexis Nunez (drums), and Peter Denton (bass guitar). The original bassist was Max Rafferty, and the founding drummer was Paul Garred. The lineup of the band remained constant until the departure of Rafferty in 2008.
Context: On November 21 2016, the Kooks announced a 'Best Of' UK Tour to take place in April and May 2017 to mark their tenth anniversary as a band, in which they were planning to perform hits, b-sides and brand new music. To coincide with the tour, on March 31 2017 the band announced the upcoming release of The Best of... So Far, as well as releasing "Be Who You Are", one of two new songs included on the compilation. Pritchard stressed that this compilation and tour did not signal the end of the band, stating, "It's been the greatest pleasure to work, travel, fight, hate and love the best and most talented people I've met in my life. It's the greatest job in the world and we don't intend to stop any time soon." The two new tracks were produced by Brandon Friesen, who has also been overseeing sessions for the band's next studio album. Consisting of songs written by Pritchard while the other band members spent time with their families, the new album is deemed to be more of a band effort, as opposed to Listen which was constructed individually. "This one's very much 'us' - all rehearsing songs, all arranging songs, all playing together. It's got the same sort of energy that we had on our first couple of albums, which we were probably running away from a little bit for a while, but now we've gone back to it," said Pritchard. "Brandon Friesen, our producer, has taken more of a production role than me, so I won't be taking the credit. On Listen, me and Inflo worked together everyday. But this one's been much more of a band record. It's been far more collaborative." On the 8th April 2017, the Kooks decided to start the tour with 2 pre warm up shows in their spiritual home of Brighton, a matinee gig at The Prince Albert Pub & The Haunt in the evening, both these Sold out within 2 hours on the day of the gig. They subsequently performed at the Isle of Wight Festival 2017.
Question: what was the best?
Answer: "Be Who You Are", one of two new songs included on the compilation.

Background: Miami Sound Machine is an American band of Latin-influenced music featuring the vocals of Cuban-born Gloria Fajardo Garcia (later Gloria Estefan). The band was established in 1975 originally as Miami Latin Boys by Emilio Estefan Jr. and became very successful after joining with Gloria Fajardo (Estefan) in 1977. The band had a number of albums and a string of hit singles until 1989. The band's 1985 album Primitive Love credited the band whereas their follow-up album Let It Loose in 1987 adopted the name Gloria Estefan and Miami Sound Machine.
Context: Following a massive world tour that lasted over a year (mid 1985-late 1986), tensions and rifts between original core members and zealous new members had taken their toll. Following that tour, both original MSM guitarist Wesley B. Wright and founding bassist Juan Marcos Avila had left the group, along with keyboardist Roger Fisher. Emilio was now taking a behind-the-scenes producer role and no longer performing live. What was left of the current MSM, plus new members (Jorge "George" Casas on bass, Clay Ostwald on keyboards, and guitarist John DeFaria), returned to the studio in early 1987. With only one other core member, "Kiki" Garcia, remaining, Gloria Estefan was given top billing and the band's name was changed to Gloria Estefan and Miami Sound Machine to jump on the sudden success of Gloria's unique vocal ability and bubbly personality on TV. In late 1987, they released their next album, Let It Loose, and it went multi-platinum, with three million copies sold in the US alone. It featured the hits "Anything for You" reaching number 1 on the Billboard Hot 100, "1-2-3" making it to number 3, "Betcha Say That" to number 36, "Rhythm Is Gonna Get You" to number 5, and "Can't Stay Away from You" to number 6. "Can't Stay Away from You", "Anything for You" and "1-2-3" were all top charting singles on the Adult Contemporary hits as well. Another world tour began and the group traveled for the first time to Europe, South America and an even more extensive tour in the United States, culminating in a finale with massive sold-out concert in their hometown of Miami, Florida, which was recorded and later sold on VHS. By 1988, founding member "Kiki" Garcia quit. With no other core members remaining other than Gloria herself, the "Miami Sound Machine" moniker was to be used from that point on for concerts and live performances only. In 1988, after the worldwide chart success of single "Anything for You", her Let it Loose album was repackaged overseas as Anything for You. It became the band's first UK number 1 album, selling over a million copies. It was the biggest selling album of the year in The Netherlands, staying at number 1 for 22 weeks. The album also took top honors in Australia and Canada, launching Gloria Estefan to superstar status.
