If you're still relying on what's left of Microsoft's Zune services to feed your Zune HD with fresh content... well, you'd better have backup plans. Microsoft is warning that it will shut down Zune services on November 15th, preventing you from downloading or streaming Zune media from that point on. If you're still holding on to a Zune Music Pass for dear life, you'll switch to a Groove Music Pass sometime between October 15th and the cutoff date -- you'd better get your 10 free tunes while you can, because those are going away. Also, any copyright-protected content you've downloaded might have trouble playing, since the licenses aren't guaranteed to renew.
