WEll I have a Zune and non of my songs are from the marketplace .
Why you pay money for mp3 song ,I mean I can buy the Cd So I'll get a high resolution audio track but really you can download all the songs you want for free from the internet
I don't really know the answer of your question the logic says yes but as usual Microsoft could say NO :):)
When you buy a new Zune you get a number for free songs from the market place So I guess you can try it ..
I hope this helps ..
If you buy music from zune marketplace is it yours? Can you transfer it to any none zune mp3 player?
