Norway's a-ha took "Take on Me" to the number one spot on Billboard's Top 40 in 1985, thanks to the award-winning animated video that accompanied it. Still, a-ha contributed rather accordingly to the '80s pop sound, drenching their music with bouncy riffs and employing the keyboard as the foundation to their colorful formula. Headlines and Deadlines: The Hits of a-ha assembles all of their singles together, a definite one-stop for all of their music. Combining ballads and radiant '80s pop, this set includes their most fervent offering in "The Sun Always Shines on T.V.," which hit number 20 in 1986 and originated from Hunting High and Low, the same album that included "Take on Me."

This incredibly diverse collection was Chicago’s sixth studio album and their final studio-recorded double album to date. Cited for its jazz excursions, Chicago VII reached No. 1 in the US and included three stand-out hits including Searchin’ So Long, Wishing You Were Here and the first single penned by trumpeter Lee Loughnane Call on Me, which reached No. 6 in the US.

String Driven Thing may have disintegrated when Chris and Pauline Adams departed, but Graham Smith didn't let that deter him. He rebuilt the band from the foundation up and shifted the focus from progressive folk to a more straight-ahead rock & roll format, a sonic sensibility helped along by vocalist Kim Beacon, whose Rod Stewart-styled vocals provided a front to the heavy-hooked guitar-driven songs. The new format didn't win many points with the band's old fans, but String Driven Thing's more pop-oriented sound fit perfectly with the mainstream marketplace's own drift away from the prog-tinged seas that the band once sailed so masterfully.

Let's Talk About Love is the fifth English-language studio album by Canadian singer Celine Dion, released on 14 November 1997, by Columbia/Epic Records. The follow-up to her commercially successful album Falling into You (1996), Let's Talk About Love showed a further progression of Dion's music. Throughout the project, she collaborated with Barbra Streisand, the Bee Gees, Luciano Pavarotti, Carole King, George Martin, Diana King, Brownstone, Corey Hart and her previous producers: David Foster, Ric Wake, Walter Afanasieff, Humberto Gatica and Jim Steinman. Let's Talk About Love includes Dion's biggest hit, "My Heart Will Go On". Written by James Horner and Will Jennings, and serving as the love theme for the 1997 blockbuster film Titanic, "My Heart Will Go On" topped the charts around the world, and has become Dion's signature song.

Animals is the tenth studio album by English progressive rock group Pink Floyd, released in January 1977. A concept album, it provides a scathing critique of the social-political conditions of late 1970s Britain, and presents a marked change in musical style from their earlier work. Animals was recorded at the band's studio, Britannia Row, in London, but its production was punctuated by the early signs of discord that several years later would culminate in keyboardist Richard Wright leaving the band. The album's cover image, a pig floating between two chimneys on Battersea Power Station, was conceived by bassist and writer Roger Waters, and photographed by long-time collaborators Hipgnosis.

Delivered in the wake of Phil Collins' massive success as a solo star, Invisible Touch was seen at the time as a bit of a Phil Collins solo album disguised as a Genesis album, and it's not hard to see why. Invisible Touch is, without a doubt, Genesis' poppiest album, a sleek, streamlined affair built on electronic percussion and dressed in synths that somehow seem to be programmed, not played by Tony Banks. In that sense, it does seem a bit like No Jacket Required, and the heavy emphasis on pop tunes does serve the singer, not the band, but it's not quite fair to call this a Collins album, and not just because there are two arty tunes that could have fit on its predecessor, Genesis.

Simon & Garfunkel's second album, Sounds of Silence, was recorded 18 months after their debut long-player, Wednesday Morning, 3 AM – but even though the two albums shared one song (actually, one-and-a-half songs) in common, the sound here seemed a million miles away from the gentle harmonizing and unassuming acoustic accompaniment on the first record. In between, there had been a minor earthquake in the pop/rock world called "folk-rock," which resulted in the transformation of their acoustic rendition of "The Sound of Silence" into a classic of the new genre, complete with jangling electric guitars and an amplified beat that helped carry it to the top of the charts.

The Nelson Mandela 70th Birthday Tribute took place on 11 June 1988 at Wembley Stadium, London, and was broadcast across 67 countries to a worldwide audience of 600 million people. Mandela was still an imprisoned anti-apartheid revolutionary at the time of the concert, but the event is considered a pivotal step leading to the eventual release of Mandela, in February 1990, following 27 years of incarceration. Unlike the Live Aid concert a few years earlier, the 1988 concert was not primarily a fundraiser (even though it made £5million) but an event intended to raise the awareness worldwide of the injustice occurring under the apartheid regime in South Africa at the time. Most pertinently, it was staged to highlight the lengthy imprisonment of Nelson Mandela and others senior ANC members, who had been arrested and held for attempting to change the system almost in the country 30 years before.
