Can I use Offline music playback and the stopwatch at the same time?

[stealthbr]

Is it possible to time my runs/work out while listening to music stored in my Android Wear smartwatch device? Meaning, if I start a song, then open up and activate the stopwatch, will the song continue playing or must I have that specific card open and active at all times for the song to continue playing? Can the music continue playing in the background?

Thanks!
