Where Apple Music fits
Use it when building a listening library around Apple's music service.
Check before you choose
Check device support and regional subscription conditions before moving playlists.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Regional rights and device support determine what a streaming service can provide. A personal media server is a different choice from a subscription catalog, and a free app does not mean every title is included.
