Microsoft has upgraded their Zune Pass music subscription service by providing subcribers credits to “purchase” or download and own ten songs. This is very cool, and I am looking forward to taking full advantage of this offerring. I’ve had a Zune Pass for a while so I have downloads a bunch of music, and I think that Microsoft should make easy for me to “buy” the music that I have already downloaded by simply right-clicking the track and clicking buy, however for some reason this feature does not exist. So, Microsoft, if you are listening, take this as a feature request.
