The best pop song ever written? | Reviewer: Anonymous | 2/15/11

It's a lyric with dark, sad, lonely, regretful, realistic melancholy, fading out to a repetitive yearn in monotony, all sung with the unmatched voices of the ABBA sisters to a sublime pop melody by Andersson and Ulvaeus. Absolutely stunning: if ever there was an underrated pop song, this is it. How come it is not a classic?
