All together, our generous valuations of the entire major music rights industry – including both recorded and publishing catalogues – comes to $27bn.
If you had ownership of the kitty Softbank used to buy ARM, that would leave you a measly $5bn in change to pick up as much of the independent sector as you could muster. Which would be nigh on all of it. In other words, the amount Softbank just paid for ARM would, by and large, buy you the entire history of music rights. Just like that.
