If you're not familiar with what on earth Groove, more formally Groove Music, is, you would be in good company. Put it simply, it's the new name of what was once called Xbox Music, since it wasn't available only the Xbox only anyway. If you haven't heard much about it since the renaming almost a year ago, that's because it hasn't exactly been given some major love. Microsoft is now trying to catch up by giving users what is said to be a most requested feature. Your Groove, in a nutshell, is Groove Music's own version of a recommendation system, both for tracks already in your collection as well as new, unexplored ones.
