I like Abba. Better than many popular rock acts. Good songwriters, good singers, mass appeal out the gazoo.
Its all music, even the mindless stuff.
I do find the music and entertainment industries obsession with making money and producing mostly mindless garbage these days appalling though. Rock music was a catalyst for that no doubt. I might dislike the corporate warlords, but not the musician pawns that end up successful as a result in general, though I am indifferent to most these days. Music can just be fun though. I love a good pop song still despite all the dreck that runs the system as a whole.
