My mom was crazy about Abba as well :) I guess every girl back then, right?
But I was more excited about exploring my Dad´s music collection, which lead me to Led Zeppelin, Doors, Jimi Hendrix, Pink Floyd... that was a huge influence for me and I still love that kind of music, even though my taste in music became harder 🤘
I do think yes, Abba was very populair :) My taste is mostly the harder rock too :) Thank you !!
