I think perhaps a well written letter and collection of signatures?

Try and get as many serious producers and DJs, label owners etc., in on it.

Just an explanation of why the current system is flawed, and some ideas on how a system could be set up to benefit clubs, DJs, labels and producers alike.

Mind you - I bet nearly none of you write down all the tracks you play when you DJ and then send it off, do you? You should... as it's the only way of any performance royalties getting back to the producer.
