The Zune Pass ($14.95 a month; $150 a year) allows unlimited music downloads to your computer, which can the be transferred to your phone. But what has been vexing me for the last few weeks of using my Samsung Focus/HTC HD7 is that there was no obvious way to use my Zune Pass on the go.
For example, say I'm in the store, hear a song playing and ID it with Shazam. I can then go to the Zune Marketplace to buy the song or use my Zune "credit" (you get 10 per month)--but no option to just download the song. This meant I would have to go home, fire up the computer and download the song that way. Huge FAIL.
Well, turns out I was wrong: you can use Zune Pass on your WP7 device. Microsoft just completely hid it, making buying/using credit as the only obvious choice. While we hate to speculate the worst, it sure looks like MS is purposefully deceiving us a bit here, steering us towards paying for music.
Anyways, watch the video tutorial to learn how. And if you don't have a Zune Pass, you may see why it's so cool to have one.
