Serato DJ is a famous and useful DJ tool. Apple Music is one of the best streaming music services you can find. If we can DJ with Apple Music using Serato DJ, that will be a nice thing. But can we? There is no official method to do that. But here we find you 2 methods to mix Apple Music with Serato DJ.

Solution 1: Synchronize Apple Music songs to TIDAL
Although Serato DJ doesn't support Apple Music, it supports TIDAL and SoundCloud. So, we will introduce a solution to sync your Apple Music playlists to TIDAL. To do that, you need a TIDAL subscription and of course an Apple Music subscription. Please note that you should update your Serato DJ software to the latest version.

Now, the key is a service called Soundiiz, which serves as a middleman between all of the current streaming services, such as Apple Music, Spotify, TIDAL, SoundCloud, and Youtube Music. Soundiiz can convert all the playlists that you currently have in those services to TIDAL. Soundiiz provides the automated transference of playlists, as well as a single interface as which to manage and synchronize between this music from those streaming services. After you sign up to Soundiiz, use it to transfer your playlists to TIDAL, you can then access the Apple Music songs within Serato DJ.
Solution 2: Convert Apple Music to MP3
This solution is to convert Apple Music to MP3 format so that you can directly import Apple Music to Serato DJ. Here you will need TunesKit Audio Converter. Here are the instructions for the conversion.

Step 1 Add Apple Music to TunesKit

First, download TunesKit Audio Converter from the link above Then launch TunesKit, and from the main interface, you will see three icons. Here's what they for:

1) This Music Note button is for importing iTunes library audios to the Converter.

2) This one is to add local audios to the Converter.

We recommend MP3 but you can make your choice depends on what actually you need.
