I will confess here that there are a few Bands that I never "got." The rest of the World swears they are geniuses, etc. and I just don't get it. My own "Overrated" list. Please don't pick obscure or blatantly obvious (e.g. ABBA for your list - just stuff that was and is critically acclaimed or had a wide following. Note too that my list kind of dates me
The Beatles - yes, I know. heresy. I just don't care if I never hear another Beatles tune the rest of my life.
Bob Dylan - I am at a total loss as to how this guy ever acheived any success at all.
Jimi Hendrix - Merely loud, not great. Dying young was a terrific career move IMO.
Sting - Boring beyond belief
Journey - this band is perhaps my all time least favorite. They are total channel-changers for me. Treacly and awful in every respect.
There are dozens of others, but these stick out for me.
