I’m talking about consensus opinion. If someone’s favorite band is Men Without hats, I won’t tell them their choice sucks. It belongs to them. But there is such thing as consensus opinion.
Does it mean anything?
It says more to me about exposure than quality.
If all we're talking about is 'consensus opinion', i.e. popularity, then sure - those are probably the three 'greatest' rock bands. That seems like a silly thing to even discuss though.
Of course if we're just talking about popularity, we have to list Elton John ahead of Zeppelin and Pink Floyd/Queen/The Eagles ahead of the Rolling Stones. Also Drake is the greatest musician of all time.
