"Pop Life" is a 1985 song by Prince and The Revolution.
 It was the second US (and final UK) single from their 1985 album, "Around the World in a Day", reaching number 7 in the US charts.
 The song starts with a faded-in synth line and quickly starts the main tune.
 The easy groove is achieved with a smooth bass guitar and piano embellishments.
 A drum machine provides handclaps to make the song danceable.
 "Pop Life" was recorded before "Purple Rain" was completed, indicating the new direction Prince wanted to take after the success of that album and film.
 Drums on the song were played by Sheila E. in tandem with Prince's then-drummer Bobby Z., bass was played by Brownmark, keyboards were played by Matt Fink and Wendy & Lisa provide backing vocals in addition to guitar and keyboards respectively, Jonathan Melvoin played tambourine and the rest of the song was performed by Prince.

'"Flavour of the Old School"' is a song by British R&B recording artist Beverley Knight, released as her debut single from her debut "The B-Funk" (1995).
 The track, which peaked at number fifty on the UK Singles Chart when it was released in March 1995, was accompanied by a low budget music video that saw Knight in the recording studio singing directly into the camera.
 It was re-released however in October 1995, supported by a new video and strong support from urban radio.
 The song went on to become Knight's first top 40 single, peaking at number thirty-three in the official UK Singles Chart.
 The song later reappeared on the b-side of Knight's 1999 single "Made it Back".

"Sign o' the Times" is the lead single from American musician Prince's 1987 album of the same name.
 Despite being negative in nature, the song was originally intended for two separate Prince albums meant to be released in 1986, that were both shelved: "Dream Factory" and "Crystal Ball".
 (Many of the tracks from both of these albums ended up on the album "Sign o' the Times".)
 Prince sings and performs the entire track all by himself; however this was one of the songs where he removed the other band member's contributions.
 In this case Susannah Melvoin's.
 "Sign o' the Times" was reportedly written and composed on a Sunday, when Prince usually wrote his most introspective songs.
