If you listen to the lyrics they are quite disturbing. Light frothy pop tunes but with lyrics about divorce, relationships breaking up, unrequired love, regret, loneliness. If you listen to all of Abba Gold it can get quite depressing.
Abba were a fantastic pop group. Once you clear awy the hen party shit nadc that goawful mama mia atrocity, and listen to the actual songs you have to accept that what they were doing was light years ahead of anyone else producing poop music at that time.
The songs have stood up so long because they are so well written and produced. yes some are cheesy but that goes with the territory.
I have a soft spot for S.O.S., because it came out while my body was being used by Swedish (and other) students for holiday romance. It was great - when my British girlfriend that year had been trying to play head games, I simply went out and pulled a top totty beauty. She was off the richter scale of gorgeousity, and her friends were lovelies too. I told the English bird to wait because I didn't want to spoil a lass's holiday, then after Ingela had gone I dumped her anyway
