The problem with lists like this is they are invariably bullshit. So our prime objective was to make sure we didn’t do a bullshit list.
I’m not saying we did a scientific one either. Because that isn’t possible — actually, it is, if you wanted some compilation of who sold the most records/concert tickets/has the most fans/got the most death threats, etc., and someone could come up with a bunch of very empirical metrics and create a “heat index” or something, and could deliver an actual scientific ranking! But we, um, didn’t do that.
In fact we didn’t even, technically, do the “we.” I picked everyone this collection.
But from time to time we add another one to this list. And we'll keep going.
