In 1986, when I was 15, a 12in single cost roughly £2.99 – the equivalent of just over £6 today. And unless you were loaded, you didn’t just buy records willy-nilly. You chose carefully and coveted what you had. (You also taped loads of them off the radio for nothing, but that often required the will and patience to sit through Bruno Brookes).
Anyhow. I’m not claiming five quid a month is insignificant: it’s more than many can afford. But in this case it’s bloody cheap for what it gets you. The problem for Spotify is that no one wants to pay for anything they access via a computer – and when they do, there’s a permanent level of resentment bubbling just under the surface. Hence the anger about “only” getting 10 hours of free music.
