Is there a way to use the 10 free songs on Xbox Music or do you have to go through the Zune Marketplace?
Using your credits is only done through the Zune software and the Music+Video hub. The Xbox Music app will not display the option to use credits. I asked Microsoft if they will include that option when WP8.1 arrives, and they said no. Also note that when upgrading to WP8.1, the Music+Video hub will no longer be available. Thus, if you don't have WP7-8, then the only way to use the credits will be the Zune software.Is there a way to use the 10 free songs on Xbox Music or do you have to go through the Zune Marketplace?
I just updated to WP 8.1 and am able to use grandfathered credits in the xbox music app. Just browse through the store from within xbox music, press and hold on a song and select "buy". It will give you the option to use credits. I'm not sure where it saves the mp3 file as it does not show up when using file explorer on the desktop. I was able to use the share option and email the mp3 file. I'm pretty sure it will automatically download the mp3 file to my computer at home in Windows 8. Will see later today when I am home.
