In October, Microsoft announced that at the end of the year, it will be killing off its Groove Music and Music Pass services. The time is almost upon us, which means that you'll need to make your final preparations.
If you're a Groove Music Pass subscriber, Microsoft has partnered with Spotify to provide users with an easy way to transfer your library. Naturally, you can switch to any service you want, but you'll have to set up your library manually.
At some point over the last few months, you should have seen the warning in the Groove app, and even if you've clicked "No, never remind me", you've likely seen it again. But even if you've cleared out all warnings, you can click on the Spotify link in the bottom-left of the app, and follow the instructions to transfer everything you've got.
If you've purchased music, you'll have to download all of it, or else you'll lose it forever after the 31st. Here's what you need to do (via Microsoft support):
Open the Groove app on your Windows 10 PC and select My Music.
Select Filter > Purchased.
Press and hold (or right-click) the item you want to download and select Download.
Find your downloaded files in File Explorer at This PC > Music > Purchases.
The good news is that the Groove app will continue to function, and it will be able to play music that's stored locally or stored in OneDrive. The obvious solution would be to move your newly downloaded music to OneDrive, and you'll still be able to play it from all of your devices. Unfortunately, this makes for a complicated solution if the rest of your music is in Spotify. Luckily, most streaming services offer a tier that allows you to upload your own music.
