You carry some unhealthy baggage or have some 60's/70's envy. The Beatles I can understand some finding them overrated. I disagree, but some don't care for their many pop-oriented tunes. But there body of work is outstanding.
Now, if someone dislikes Pink Floyd, well, you need help.
I like most of the groups being listed. One group that I never cared for is Steve Miller Band. They ripped off (called it a tribute to) Free's "All Right Now" and I've never found them to be much of a band. And his vocals = meh.
