Thanks for the links, Hugh2!
After 1 listen, I liked the second track "Don't Shut Me Down"; after 1 listen the first did nothing for me.
ABBA is a top 20 all-time artist for me. I took significant abuse from my friends for liking them in the 70's (in the US).
I think history has proven that I was onto something.
I like melodies, and ABBA recordings had actual tunes, with groundbreaking production.
(Aside: I think Cole Porter would have been proud to have written "Head Over Heals"; "The Visitors" is a top-ten all-time album for me.)

I can still remember my euphoria while listening on headphones, the music exploding in my ears, and the rush I got, the first time I heard "SOS", "Mamma Mia", and "When I Kissed The Teacher".
It was clear to me they had gone to school on Brian Wilson and the Beach Boys (something I've since seen confirmed by the guys in a documentary).
My favorite ABBA track is "Why Did It Have To Be Me", an obscure track featured in the film "Montenegro".
I'm posting a live version I just found; to my astonishment, they were a great live band also. (IMO)

I like that all four of them sing on the studio track (unusual), I like the sax, and I especially like the syncopation in this shuffle.
I didn't care then what people thought of me for liking ABBA.
I certainly don't care now.
I like what I like. It has worked out well for me,
since I am the one who pays for my records / CD's etc.
