Why Spotify Wants Blockchain & How All The Music Industry's Blockchain Dreams Can Come True

1During the course of its recent acquisition spree, Spotify bought Blockchain company Mediachain Labs, hoping that the company would be able to solve some of its wayward copyright issues. But there is evidence that both Spotify and the music industry may not fully understand how blockchain tech actually works, writes David Gerard.

Spotify’s been on a bit of a spending spree lately, acquiring content identifiers Sonalytic and recommendations app MightyTV, and now Blockchain company Mediachain Labs.

I specify “Blockchain” with a capital B and no article, because that’s the sure tell that there’s no evidence anyone involved has any idea how this thing is going to work or do anything.

The problem Spotify [has] is that nobody knows who the hell owns a lot of the songs. Streaming produces a veritable firehose of data that looks like what publishers and record companies want — the usually-wrong idea that if you only had more data you could solve all your problems! — but is actually of questionable quality, and the collection societies are getting buried in it.

The data is problematic enough that Spotify just settled one suit over this with a $30 million payment.

I’m presuming that, despite the hype, Spotify don’t actually want Mediachain for blockchains, but for things like the attribution engine and the quest to get cleaned-up and useful data out of people, because there’s no way the Blockchain stuff can scale to workability in practice.

The way Blockchain hype works is that advocates promise all sorts of unlikely outcomes — money directly deposited in artists’ accounts directly upon an iTunes purchase or Spotify play, transactions that occur “nearly instantaneously” (“in less than one second” — an unworkably short block time, but that’s the least of the idea’s problems) and directly, without intermediaries. All you need to do is clean up the data, and you get all the magical stuff!

It’s not just music — across many industries, the main Blockchain promise is magic after full availability of properly cleaned-up data. The actual problem in every case is cleaning up the data at all. The proponents’ business goal is to become the organisation controlling the newly cleaned-up data, with a monopoly maintained by network effect. The barrier that such efforts founder on, over and over, is that no industry’s players want to create a new central octopus.

Of course, none of the magical outcomes are feasible in the first place:

  • No single blockchain can possibly scale to the whole music industry. Spotify played a billion streams a day by mid-2015.
  • Apart from the metadata itself being huge, there’s the encoded details of all the hundred-page contracts. And who will pay for the computing resources to execute all the smart contracts for each song played?
  • “Where there’s a hit, there’s a writ.” You sue and win. How is the “immutable” blockchain corrected?
  • What’s your security threat model? This one never seems to be mentioned, and we’re talking about real-world money here. How is your blockchain kept secure against hostile attackers, say, someone who has the money to bring a 51% attack against a Proof of Work secured chain? How will you clean up the mess after an attacker uses bugs in your smart contract language that they knew existed and you didn’t?

Every real-world attempt to do this has fallen flat on its face. Imogen Heap’s hugely hyped Mycelium initiative for “Tiny Human” took in a total of … one hundred and thirty-three dollars and twenty cents. The number “133.20” needs to be burnt into the music industry’s collective consciousness until the end of time.

Music collection societies tried to create a Global Repertoire Database in the early 2010s, but scrapped the idea in 2014, as nobody wanted to create and fund a new central octopus, even though they all knew they desperately needed something that did this job.

I’ve noted before that the only music industry blockchain paper I’ve seen that isn’t garbage (and in the course of writing a book on Blockchain I have read thousands of pages of the worst and stupidest white papers you could imagine) is Blockchain or the Chaingang? by Jeremy Silver. It’s not technically perfect, but it points out the bloody obvious reasons that most music industry blockchain dreams are simply infeasible.

MusicTechFest’s #MTFLabs: Blockchain meeting in August 2016 foundered on the problem that the various players have always had contradictory interests, viciously fought, and moving the perpetual industry civil war to the blockchain probably won’t help much:

In large part due to the inherent fault lines within the topic itself, the lab turned away from seeking “solutions” to discussing concepts such as “copyright”, “ownership” and “security”, as such words can take on very different meanings based on one’s professional background and personal frames. Differences in perception revealed seemingly intractable disagreements that were unlikely to be resolved in a weeklong discussion about an incredibly complex technology.

They propose: “a modular approach, where specific problems are solved incrementally, building up an open and transparent meta-system ensuring the individual systems that address the sub-problems use open standards and globally acceptable and accessible data, for example residing in one or more blockchain-based systems.”

This is almost certainly the right answer, except without a blockchain. In any industry, if your big goal is cleaned-up data across multiple organisations, the only approach likely to get you there is creating a data schema that is so obviously and elegantly the right thing that everyone just adopts it themselves, and a regulator eventually says “hey, use this schema.” Note lack of blockchains. (This is the usual approach in computing, though even there companies routinely try to set themselves up in the role of central octopus. And, of course, every musical Blockchain initiative has “become the new central octopus” as the only way they could work.)

As Matt Levine at Bloomberg noted: “The word ‘blockchain’ has managed to make that boring back-office coordination work sexy, which means that it might actually get done.”

One problem nobody seems to mention: incumbents will treat technological change as a threat and resist it as bitterly as they have every other technology. Silver notes major labels refusing to look at BitTorrent data his firm Semetric was offering them, even though it was an excellent predictor of sales, for fear of appearing to validate BitTorrent in any manner.

And the other problem: the record companies are still way too interested in keeping their actual deals secret. Because, as IBM was actually surprised to find out with their Hyperledger blockchain project, real-life businesses of all sorts don’t want to share data even with all participants in their blockchain, but only with the people each specific deal is actually with. Funnily enough.
