Hmmm.. Xbox Music will have such a feature, so I know almost all of my music will be available wherever Xbox Music is supported. But on Android, that's still "to be released in the future".
My question - will Google match WMA files? You cannot upload them, DRM'd or not (I don't think I even have any DRM-free WMAs though), so my Google Play music content is far less than I have on my desktop.
I cannot wait for Xbox Music on Android though. The old Zune Pass was awesome, and I still currently get to retain the Keep 10 aspect... I'll have to continue to use the Zune app though, even on Windows 8, since the Xbox Music app does not support the Keep 10 credit system. And my Zune HD does get to enjoy any Xbox Music features.
Holding out hopes that a Windows Phone 8 or Windows RT 3" or 4" PMP (wifi only) device will be brought to market by at least one manufacturer.
I just don't want to give up the Zune Pass. I can't ... not until Microsoft kills it off. And I actually prefer having a dedicated mp3 player, even if I also have a smartphone.
Perhaps I won't have to wait any longer than a year for Xbox Music to land on Android - as there are Android PMPs out there, though it's a fairly dry market. But any Android phone more than a year old can be had for good retail (no contract) prices. hmm
Yes, that was a massive segue. Deal with it.
