Last yr, I had the misfortune of losing all my playlists after I moved from Apple Music to Spotify. For me, playlists are necessary. They’re snapshots of a certain period in your life; possibly your summer of 2016 had a soundtrack. But traditionally, streaming music services don’t make it easy to take your playlists with you to other platforms.

You can imagine how joyful I used to be to see that Apple Music has created latest playlist uploader through the Data Transfer Initiative (DTI), a group founded by Apple, Google, and Meta to create data transfer tools. The Digital Markets in Europe Act requires these designated “gatekeepers” to fund data transfer tools as a part of a broader solution to Big Tech’s strategy of blocking users from their platforms.

Finally! There was only one big problem. The tools don’t work with the world’s hottest music service, Spotify, which apparently didn’t catch the wave of knowledge transfer (or possibly the regulator doesn’t tell them to). The DTI tool only transfers data between Apple Music and YouTube Music, making it much less useful for most individuals.

DTI Executive Director Chris Riley can be fed up with Big Tech’s blocking policies. He’s trying to get more firms to join the negotiations and make their services more portable.

“Over the last decade, we’ve kind of blended into this world, just feeling trapped,” Riley told TechCrunch. “I don’t think enough people know that this is something they need to know.”

With DTI limitations in mind, Riley suggested I move my playlists from Apple Music to Spotify using Soundfree third-party tool. Instead of working directly with streaming services, Soundiiz builds portability tools through existing APIs and acts as a translator between services. Within minutes, I used to be able to connect my accounts, transfer my playlists, and start listening to my old Apple Music playlists on Spotify. It was amazing and easy.

Soundiiz allows you to transfer playlists between Apple Music, Spotify, YouTube Music, Amazon Music, Tidal, Deezer, SoundCloud, and 20 other streaming services I’ve never heard of. There’s a simple user interface for connecting streaming services and choosing the playlists you would like to transfer, including ones another person has created.

The story behind Soundiiz may explain why it works so well and cheaply. It was created in 2013 by two friends from France, Thomas Magnano and Benoit Herbreteau, who loved listening to music while coding together. In the evenings, they decided to create a music search interface with input from everywhere in the web. In the method, they created a useful tool.

They never created a music search interface, however the playlist uploader became Soundiiz.

“I had to manipulate the API and test the fit between services. And while I was doing that, I was creating playlists and moving them between services, just for me internally,” Magnano told TechCrunch. “I presented this feature to a colleague of mine and we thought, ‘Oh, this is useful to me; maybe it’s useful to someone else.’”

In 2015, Soundiiz got its big break when it partnered with Tidal, the music service founded by Jay-Z. The music platform was trying to make it easier for people to leave Spotify and join Tidal with all the identical playlists, and Soundiiz helped with that. But Magnano says they made sure Tidal also let people export playlists, not only import them — something they require from every music service API they work with.

Then a lot more people began using the service, and the founders made Soundiiz their full-time job, but they kept their values. The two founders make a living from Soundiiz, but they tell TechCrunch they’re “not looking to get rich.” Magnano says Soundiiz has never sought outside investment to keep prices low, and the founders retain control over their project.

There are limitations to the free Soundiiz though – a number of the longer playlists might be shortened (limited to 200 songs). You even have to transfer playlists one after the other, and every one takes about a minute, so transferring a dozen or so playlists can take a while. Soundiiz offers a premium plan ($4.50 monthly, which you’ll cancel after transferring) to get around these limitations.

The two founders are still the one employees of Soundiiz, regardless that the corporate has grown: Soundiiz has helped hundreds of thousands of individuals move over 220 million playlists over the past 10 years. According to Magnano, they’ve never spent a dime on marketing, but he says they’ve never had to.

“If you were to Google ‘how to transfer Deezer to Spotify’ in 2012, there was no answer,” Magnano said. “So Soundiiz became the first result in Google search when we launched, and we’ve been doing great in SEO ever since.”

Magnano says Spotify likely has more to lose than to gain by creating a playlist uploader like Apple and Google, and he doesn’t expect that to change anytime soon. However, he says that every one of those streaming services are aware of what Soundiiz is doing and are okay with it — some even promote it of their FAQs. That said, it’s unlikely that any of them would promote playlist uploaders like Soundiiz greater than this.
