It certainly seems, from the vantage of 2019, that ABBA's style of pop music deserves to be called timeless. Growing up in the 90s, for me they were the quintessential cheesy, slickly insubstantial pop group, but tastes and perspectives change and listening to this greatest hits now it's striking how terrific it is, and how direct a line can be drawn from them to all kinds of more recent pop; basically the only difference between many of ABBA's songs and the best moments of a band like Girls Aloud, say, is the production (and even that's not so different a lot of the time).
