Why doesn't it count my band?
Sometimes you only see three question marks instead of the mainstreamness in the results table. There are two possible reasons for this:
a-Because this band has no recorded listener on Last.fm
b-Because of the Meter.
Most of the data on Last.fm is made available in a form which is readable for machines but sadly, they decidednot to do so with the listener count. So the Meter has to read through the same artist page you also look at when you're on Last.fm. Sometimes this doesnt't work. I don't know exactly why but I guess it's because pages at Last.fm tend to be a little slow sometimes and the meter gives up reading them after a few seconds. Anyway - come back after a week and everything should work fine ;).
