I tried three of these tools: Soundizz, FreeYourMusic and Songshift (which only works on iPhones). All three allow you to transfer a few playlists with a limited number of songs for free, but you have to pay to move multiple playlists or bring your favorite songs and albums.

Soundizz was the cheapest of these options, costing $4.50 per month – yes, it’s a subscription service, which you can cancel as soon as your transfer is complete. Songshift also starts at $5 per month. FreeYourMusic offers a subscription plan, or you can pay a one-time fee of $12.

The services are all similar. Here’s how it worked on Soundizz when I tested the service by moving my Spotify playlists to Apple Music.

I opened the Soundizz website in a browser and pressed the Spotify icon. (I could have used a smartphone app instead.) This opened Spotify’s login interface. Then I tapped on the Apple Music icon and connected. From there, all I had to do was head to Soundizz’s Transfer tab, select the playlists I wanted to move, hit Confirm, and follow a few more steps.

If you have a lot of playlists or playlists with a lot of songs, it will take a lot of time, around half an hour in my case.

Popular music streamers have nearly identical catalogs, but your new service may not have all the songs you saved to your old account. Transfer apps let you know if there are songs that are not available. These music transfer apps sometimes match the wrong songs. So, once the transfer is complete, it’s a good idea to check your new music streaming service to make sure it’s working.
