Recently I canceled my Rhapsody subscription in favor of Spotify, mostly because the latter now offers a $15/month family plan (though it stubbornly refuses to block explicit lyrics, grumble, grumble).
Having been with Rhapsody for a couple years, I'd assembled quite a number of playlists and was dreading the thought of having to manually recreate them in Spotify. Alas, the former doesn't offer any kind of playlist-export option, which is not uncommon.
Fortunately, I found a Web tool that can do the job: Soundiiz. It's compatible with the following services:
As you've probably noticed, Apple Music/iTunes and Google Play Music aren't on that list. Fortunately, you have options: You can import playlist files from the likes of iTunes and Rdio, or any program that can generate an M3U file. As for Google Play Music, check out this tool for exporting those playlists to M3U format.
Before I get into the specifics of using Soundiiz, let me share the big caveat: In order to transfer your playlists between services, you need to sign into those services -- which means revealing your usernames and passwords.
Not wild about that idea? There's an easy workaround: change your password(s) after you're done using Soundiiz.
With that out of the way, using Soundiiz is pretty straightforward. Starting with the service you want to transfer playlists from, click the Connect button, then provide your log-in credentials. Now do likewise with the service that's going to receive the transfer.
Then it's back to the first service, where you should see a list of your available playlists. Click the gear icon if you want to see the contents of one of them, or click the share icon (the little arrow coming out of a box) when you're ready to transfer. Next, click the desired destination service, then click Convert to start the process.
I performed a handful of tests between services, and in most cases Soundiiz worked perfectly. Initially, I had to disconnect and reconnect Spotify to playlists to land there, but after that it was smooth sailing. There were all a few instances of particular tracks not transferring, simply because the destination service didn't have them in its library.
Interestingly, you can copy playlists to Soundiiz proper if you want an online repository for them. That might help if, say, you're canceling a subscription to one music service and not yet ready to migrate to another. Soundiiz can be your holding tank.
Indeed, if you need an easy way to transfer playlists and don't mind sharing your account info, Soundiiz is a decidedly helpful tool.
