Is this a good deal? After buying a Windows Phone (Lumia 900) I tend not to use my ipod anymore and the way I'd buy music was through iTunes (which I hate). I'm going off the college next year to Austin which has a pretty big music scene so I really want to be able to listen to any song whenever I want. Is buying the 100$ year subscription a good idea? I have a Lumia 900 and Windows CPU. Any downfalls or better options? I'd prefer not to pay with credit card nor through ATT every time I want to buy a song, are there Zune gift cards like apple has?
