There's a notable lack of decent apps on Samsung's smartwatches right now, but the latest addition of Spotify is going to make a big difference.
You'll be able to play music directly through the watch, either through its speakers or to some wireless headphones. Meanwhile the rotating bezel offers a way to control streams beyond the touchscreen.
Sadly there's no offline mode right now, so if you're taking it for a run then you'll only be able to use it with the LTE watches, or hope that your gym has Wi-Fi. Hopefully we'll get the option to play our offline playlists in the future.
