I have tried the Spotify app - what a joke. I can't get a single thing to sync with that, it just drains the battery and eventually fails.
So I decided to just use my computer and put a podcast on manually just so I could use the dang thing and I can find literally NO WAY to download a podcast onto my computer.
Also - Why oh why do I need to be both bluetooth linked to my phone AND on a wireless network to try to sync something onto my watch? If I'm attached to my phone, I shouldn't need a different connection to download something, and if I'm using my wifi, I shouldn't have to carry around my dang phone.
