Microsoft still isn't having much luck competing in the digital music realm. The software behemoth has announced that it's axing its Groove Music services (streaming, purchases and re-downloads) after December 31st, 2017. And unlike in the past, there isn't another Microsoft-branded service waiting in the wings. Instead, the company is transitioning everyone over to Spotify. The Groove Music app will offer to migrate your collection and playlists through an update, starting with a preview version this week and more broadly on October 9th.
