I have an old (in both senses of the word) friend who was bewildered when he in the late-70’s learned of my love for ABBA. Rock music snobs have always looked down upon Pop music. Jazz snobs look down upon Rock music, Classical snobs look down upon all other musics (except perhaps Jazz), etc., etc.
My ABBA records sit on the same shelf as my Mose Allison and AC/DC records. 😊
