Just tried the Zune pass...and a few years later still no regret
(New York City)
I first got a Zune and just tried the 14 day free pass. After the 14 days were up my music collection practically quadrupled...and it was too hard to go back. The Zune Pass introduced me to artists and musical genres that i would have never looked into before.
It's been a while now and I still have the Zune pass and never have I had any regret of having it. Plus now you get to keep 10 mp3s per month which makes the total value even harder to pass up.
Having the Zune pass also keeps your library extremely organized with all the right album art and tags etc. If I didn't have Zune pass i really don't know what i would do!
