The Official Charts Company stated that due to the immediate availability of an artist's back catalogue in the streaming era, "the concept of a greatest hits has changed, with many artists opting to re-work their hits to give them a fresh spin", comparing it to Take That's 2018 greatest hits Odyssey.
