$5 is too much, because the service sucks, and the money goes to the wrong people (another corporation, still not the artists). It's hard to find anything but crap on Napster, and when you do find it, it's improperly encoded and has a low bit rate. But, on the other hand, it's free, so all you're wasting is your own time looking for it. If they start charging for the service, then there's a lot of quality assurance they'll have to provide to justify it. And if I were a subscriber, and they didn't, then I'd be the first in line to file a tort suit against them.
