but then you get a group like status quo, who just had a laugh and did what they wanted, and they are still going now 40+ years later.
But doing what you want effects how big of a following you get. I had never heard of Status Quo until just now. But it isn't that it is impossible to have a long career in music even if you do what you want. All it means is that you won't be as popular as you would if you gave the average person everything they wanted to hear.
the complaint is about the fact that music is all about sex at the moment,
But it isn't. Only the popular stuff is about sex not all new music is popular.
by tradition, we should find our parents taste in music boring, and be obsessed with the music that comes out during our teens.
But who cares about tradition? I like what I like. Several of the bands I like have been around longer than I have. And a lot of the music that came out during my teens doesn't interest me anymore.
