my music is all in iTunes match as i dont have much space on my iPhone, one of the reasons to want to put some music on the watch so first of all i am over eager, go into the watch app and add about 10 albums, not only does it say uploading for ages but every few albums i have to delete an app as it tells me i have ran out of space. see the system size rises so guess it downloads the music to there rather than the music app on the phone. after leaving that for an hour i figured i might have over loaded it so delete everything but the first album from the watch app. it still says uploading. wait ages. delete that album and replace it with a fresh album which is the only thing uploading on it. and then i wait. and look. and wait. and try different things. notice it doesnt even pretend to be uploading when the watch is plugged into the usb on my iMac, so move it to a proper plug. leave it over night with both of them beside each other both plugged in, both on wifi. try it with the phone on its side looking like an alarm clock, and on its back so it doesnt. put the phone on dont got to sleep, and leave it on the watch app figure it might be that it doesnt get the music from the internet well, so trying to download the same album to my phone but that just whizzes round, is that coz its trying to download the album from two different places at the same time?
