Comes With Clarification would also be handy.(Correction notice)

Nokia's service will certainly affect the industry for the better, but details of its royalty allocation plans are vital

On the face of it, Nokia's Comes With Music will bring exciting new benefits to consumers and the industry alike, offering music fans a revolutionary new way of accessing tracks while creating a brand new revenue stream for its recordings.

So far so good, you might think. But try to get to grips with how the money paid to the industry from handset sales will be distributed and it is likely to give you a headache.

With the plan understood to be that majors who have signed up for the service and publishers, via the MCPS-PRS Alliance, will receive fixed payments from the sale of each compatible device, Comes With Music could well deliver the business a handsome sum of money in return for allowing users to download as much music as they want across a year.

However, what has not been made clear to all relevant parties is on what basis the majors will divide up this money to their artists and, on the publishing side, how the money will be split between the publishers - and how those publishers will then divvy up cash to the songwriters.

These are fairly basic but fundamental issues to what is one of the biggest new music services in years. But calls put in across the industry by this publication last week asking how this was going to work were met with replies of puzzlement, concern and contrasting explanations.

As MMF chairman Jazz Summers, in his usual no-nonsense way, puts it, "Everybody talks about transparency in the music industry these days. This whole deal is completely opaque."
