Does Xbox Music Pass use your Microsoft Account for payment? I really need to spend these $20 gift cards. They are beginning to pile up!
Yes, Microsoft account needed
If you purchase the song, you get to keep the song even after canceling the subscription. Songs that you purchase are DRM free and can play on anything. If you are downloading for free, those won't play after you terminate the subscription. And those downloads-for-free are only playable on Xbox Music devices.
My question is, can you download the songs to a memory card? I have a Lumia 521 and space is really tight. I've got tons of space on a memory card but nothing stores there (just videos, pictures, MP3s I got elsewhere, etc.). Windows Phone wants everything in onboard storage. I barely download any apps because my space is totally taken up. One of the apps I definitely need (Camcard) is ever growing (as I add more business cards) which means I need to dump apps as I add business cards...
