Can I put my own music onto an Android Wear watch?

[AC Question]

I have this truckload of MP3s on my phone, which I listen to using the Google Play Music app. Can I transfer these to an Android Wear smartwatch, if I can't upload them to Google Play Music, because it's not available in my region? This would affect my decision whether or not to buy a Moto 360.

Yeah, that was me before I realized I wasn't logged in
