Sharing playlists across different music platforms can be a bit tricky due to the different formats and exclusivities each platform uses. However, there are several third-party services that can help you with this task. Here's a general guide on how you can do it:

1. **Soundiiz**: This is a popular tool that supports a wide range of platforms including Spotify, Apple Music, Tidal, YouTube, Amazon Music, and more. You can use it to convert playlists by simply connecting your accounts, selecting the playlist you want to convert, and choosing the platform you want to transfer it to.

2. **TuneMyMusic**: This is another tool that supports a variety of platforms. It works similarly to Soundiiz. You connect your accounts, select the playlist to convert, and choose your desired platform.

3. **MusConv**: This tool also allows you to transfer playlists across a variety of platforms. It's a downloadable software that you can use on your computer.

Please note that while these tools are designed to make the process easier, they may not always be 100% accurate due to differences in song availability across platforms. Also, some of these services might require a premium subscription for certain features.

Remember to always respect copyright and the terms of use of your music streaming platforms when sharing playlists.
