Where Spotify fits
Use it to maintain a listening library that follows you between supported devices.
Check before you choose
Check regional content and the selected plan's offline and playback conditions.
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.
