Today, as Now 100 is released, 35 years after the very first edition in 1983, who has been included the most?
Statistics show that new X Factor judge Robbie Williams is the act who has been featured the most: a whopping 30 times; starting with Old Before I Die on 1997’s Now 37.
Next are Kylie Minogue, Rihanna, Calvin Harris respectively, who have all had more than 20 appearances.
David Guetta and Coldplay have also crossed the 20 mark, while Girls Aloud and Britney Spears have each appeared 20 times each on a Now album. The Top 10 is rounded out by U2 and Sugababes.
Now 100 is a unique venture for the series – because the two-disc set is being done slightly differently.
While Disc One is, as usual, packed with the latest chart hits, Disc Two is more a collection of the biggest hits from the Now era, from UB40’s Red Red Wine to Justin Bieber’s Love Yourself.
The first half is, as ever, peppered with the latest and greatest chart smashes – starting with Dua Lipa and Calvin Harris’s One Kiss and continuing via George Ezra, Clean Bandit and Demi Lovato, Ariana Grande, Anne-Marie and Jess Glynne.
The album is expected to sell thousands upon thousands of copies this week, as it continues to shift huge numbers of physical copies in supermarkets.
Mark Goodier, who has been the voice of Now adverts since 1992, told BBC News: “If you bought three Now albums a year in the 80s and 90s, you’d have a very good snapshot of the year in your life.
“People established that relationship with Now when they were kids and, of course, that’s very formative.”
Glynne said: “As a kid you buy those albums and it’s your everything.
“I remember when I got one with the Spice Girls and all of that and I was like, ‘Oh my God, it’s like gold!’”
In total, it would reportedly take over 250 hours to listen to all 100 Now albums in full; while 120 million have been sold in the UK since it launched.
Now 100 is out now.
