It's good for you to let your friends think what they think and continue with what you like!
Music from the past can have such an appeal since it is quite different to what we know and hear today.
All good and all, but we have a legacy of some great musicians.
Funnily enough, in (specific corners of) dance music, I see/hear repeating cycles of about 20 to 25 years. Since most of the music in these little corners is less recognisable by many, the younger generations go nuts on tracks from 20 years ago thinking it is new 😆
