Yes, I was and still am a big Fan of ABBA recordings. All the musicians I hug out with were in awe of their records not necessarily for the songs but for the SOUND.
Me, I liked 'em both and still do.
Years ago I got to sit and listen to a recording engineer who had worked with ABBA's legendary Tretow. He filled us in (it was a workshop for recording) how Tretow had made their vocals literally JUMP off of the record. Very ingenious that Tretow chap!
ABBA is great. Their songs are addictive and never get old, at least for me. When an ABBA song comes on I have a hard time turning the channel.
