The Radio Station Method
Periodically KROQ and the other stations have their listeners vote for the station's top artists of all time.  One problem is that people have short-term memories and are biased towards whatever bands are popular at that moment, much as the year-end lists are biased towards the latter part of the year.  As a result you get some flash in the pans up there with the all-time greats, and that ain't right!

The RadioHitlist Method
Using the RadioHitlist database I decided to rank bands based on the number of songs they have in all of the countdowns (that I have).  It seems a much more fair and objective method, although I don't like that a song that is at the bottom of a list counts as much as one at the top, but I couldn't think of an easy way to weight them.

So without further ado, here are the top artist countdowns:
