The decision to block access to napster here was made at a higher level than
this writer, so I can't speak to the policies involved. I can however,
without further comment, reproduce the access list that seems to have
effectively cut them off:

    deny ip 208.49.228.0 0.0.0.255 any
    deny ip 208.184.216.0 0.0.0.255 any
    deny ip 208.49.239.240 0.0.0.15 any
    deny ip 208.178.175.128 0.0.0.7 any
    deny ip 208.178.163.56 0.0.0.7 any

It's the second line that gets most of the hits.
