Possibly, however trying to wring every last cent out of their fans based on a simple supply/demand model might not work out too well in the long run. There are a lot more choices out there, so if the fans get the feeling they're just a bunch of dollar signs, and that the band is in it just for the money, demand might dry up. Keeping the price lower could keep demand higher by helping to sustain their popularity and keep the fans around longer.

Sounds great, except there are still a lot of places that have stupid password limits, like no more than 8 characters, or no special characters, and so on. So you still end up with a bunch of unique passwords, and have to find a way to remember them all.
