On October 22, Duran Duran are set to release their 15th studio album Future Past, their first in a new record deal with BMG. To date, Duran Duran have landed 10 Top 40 albums on the Official Chart, plus 30 Top 40 singles. View Duran Duran's Official Chart history here.
Kylie's most recent album, 2020's DISCO, became her eighth Number 1 album in the UK. She's now only behind Madonna as the female solo artist with the second-most Number 1 albums in the country. However, Kylie is the only female solo act to land at least one chart-topping album in five consecutive decades - 80s, 90s, 00s, 10s and 20s.
