Groove Music [1] (formerly known as Xbox Music, Zune Music and Microsoft Groove), Groove Music Maker [2] (an unreleased Windows 10 app), Office Groove [3] (a.k.a. SharePoint Workspace) or Groove (now known as OneDrive for Business - the service formerly known as SkyDrive Pro) [4].
I'll do you one better. Before all of that, Groove was a workgroup product, started by the famous Ray Ozzie, which was acqui-hired by Microsoft, and then spiked. It was brilliant. There's been nothing like it since. (Except maaaybe Slack.)
My favourite example has to be Groove.
