Oh it gets better. If you look at the appx package names for "Groove music" and a couple others they're still Microsoft.Zune prefixed

Thats because the team that wrote Groove Music (and Movies & TV) originated from the Zune desktop player and Windows Media Center. In fact it still used a lot of core code from the Zune days for things like library management and DRM.

The Zune desktop app has to be the best music player I've ever used, it was awesome. I continued to use it long after I moved on from my Zune HD. Sad to see something so awesome abandoned.

Appx package names seem almost entirely uninteresting and most consumers will never look at them. Why would anyone bother changing them?

Disclosure: Microsoft employee, but not on Groove (or anything related to appx packages for that matter)

The thing is, they created the name when Zune was already dead lol
