This man gets it. Flickr/@HayeurJF There is a fundamental problem with music-streaming services such as Spotify or Apple Music.

It's not that streaming music often fails to properly value artists' work — though there have been grumblings for years about the amounts paid out by Spotify to rights-holders.

And it's not the overall cost of a lifetime of a streaming service, though Apple founder Steve Jobs hated streaming services for exactly this reason. In one of his best-known keynote speeches, he railed against the idea of "renting" music, arguing that you end up paying for your favourite songs thousands of times over.

It's not even the limited selection of music available to stream, though even the best and most comprehensive streaming service is unable to acquire the rights to everything you may want to listen to.

Permanence is everything

Let's imagine for a second that Spotify goes on living for another 30 years. That's a pretty long time for any company to stick around — especially in an industry as volatile and prone to disruption as the intersection of music and technology.

Barring any unfortunate accidents, that would make me 53 when the company finally closes its doors in 2045. And then what happens? My entire music collection, painstakingly built over three decades of careful listening — gone forever.

Can Spotify CEO Daniel Ek promise your music will be safe 20 years from now? Getty Images Music is not like a film, or a book, that you consume perhaps half a dozen times at most. It makes up the backdrop to your life. Whether it's the early teenage freedom that accompanied The Killers' "Jenny Was A Friend Of Mine," or the "Indecision" by Sampha soundtracking a period of listless post-graduation melancholy — music is linked to almost every major moment of my existence. And just listening can take me back at any moment.

When you're "renting" your music, the problem isn't that you're paying for your favourite music thousands of times over. It's that you have no control over it. You could lose it at any time, through no fault of your own. In 20 years, CEO Tim Cook's successor at Apple could decide the company needs to tighten its belt and wipe out 100 million people's libraries overnight. That uncertainty undermines music's most powerful quality — that it's a concrete link to the past.

Of course, the alternative — owning your music — has its own problems. It's expensive, and it takes up significant amounts of storage space. Music streaming also offers powerful convenience — so much so that I'll admit that I will sometimes use Spotify when I'm out and about.

And with owned music, there's always the risk that you lose the hard drive your collection is stored on — and with it your years of careful work. Spotify, Apple Music, Tidal et al don't have this problem (though the risks can be mitigated through careful backing up).

So, yes, ownership of music isn't perfect. But ultimately, when I'm older and looking back upon my life, I'll want my music collection more than ever. And the custodianship of that is not a responsibility I'm willing to grant Apple — or anyone else.
