That's an interesting point about sampling artists
Summercity. The major labels have tried, and failed, with courtroom battles over this; at least in U.K. & U.S. (I know Oz copyright law has varying elements).
I'm pretty naive about these things, but at face value the Larrikin/EMI decision does appear to create a pretty dangerous precedent. I don't have much time or sympathy for any of the bleeding-heart major music houses, but in this particular instance I do hope EMI appeal the decision and I wish them well. As for Larrikin; they're no better than ambulance-chasers
