I’ve done a several interviews in the last few weeks where journalists have asked about the value of music, as if this is a major cause for concern.

I’ve never really worried about this, and here’s why:

We just got our water bill. Water is clearly valuable – we would die without it – but it isn’t always expensive. In the last six months, we used 66,000 litres of tap water, at a price of just over £162 (including standing charges).

Water is fairly readily available where I live. It falls out of the sky. Indeed, an average of 736,000 litres of water land on my house and garden each year.*

There’s also a stream at the end of the street which must carry far more than that, and I live walking distance from the sea. Let’s forget about these sources though: the hundreds of millions of people around the world struggling to survive without clean drinking water wouldn’t appreciate it if we confuse this with the stuff coming out the tap.**

Still. In the park at the end of the street, there’s a drinking fountain. There’s also a cafe where you can get a plastic cup of water, free of charge. If these are closed, the reservoir is at the top of the hill. With some inconvenience and fewer baths, I could get free water if I wanted.

The water supplied to my house costs about 0.1 pence per litre. It’s metered, although some people are still on the “all you can drink” subscription. Whichever tariff you’re on, you’re allowed to put the water in a mobile device or “bottle” and take it out with you.

The bottled water we buy from the supermarket is 8.5p a litre***. I’m fairly sure this is tap water, marked up to more than 80 times the price, but it still seems hilariously cheap when you can pay ten or twenty times this amount for a glass bottle of fancy water, still or sparkling.

The cafe in the park offers bottled water at £3 a litre. This is 3,000 times the price of tap water, and it’s offered right next to the big jug of free stuff. Still, business is good. People buy the bottles. If you’re willing to leave the Shire, you can pay a lot more.

What I find really interesting about all this is that most of the bottled water brands (or at least the companies that currently own them) entered the market when cheap, good-quality tap water was already available to almost**** everybody in the country, apparently unfazed by this massive pricing disparity.*****

I’m surprised, then, when people tell me streaming music is somehow unsustainable, will completely replace downloads or is devaluing music. I don’t have to pay anything to listen to the radio. People give me free CDs. I can listen to most things on Spotify when I’m at my computer. I still buy music, both as downloads and occasionally as physical products in almost every imaginable format. I buy them with the money I make from selling recordings, and while I fully expect to have to keep looking for new ways to do it, I have no plans to change career.

With apologies to Information is Beautiful.

Footnotes

* You can figure this out yourself: multiply the length of your property by the width (in meters) and multiply this by the annual rainfall in mm. Then check the order of magnitude about six times because it seems like A LOT of water. I live in one of the least-rainy parts of the UK.

** With a big tank and a filter we could be self-sufficient, but this over-simplifies the clean water problem. To live off the grid, we’d also have to disconnect the sewer. That’s where things get problematic, especially if any of the neighbours were planning to use the water from the stream at the end of the street.

*** Including delivery.

**** The near ubiquitous availability of bottled water makes us less inclined to install drinking fountains in public places, which may not be a good thing.

***** My local water company announced a profit of £79.9m last year, up 147.7% on 2011. The global bottled water industry is doing fine.
