Hi guys,
together with this month's PC Zone I received an offer with 35 free music tracks to download from emusic.com
Once finished downloading them, just cancel the subscription (they ask you credit/debit card details when you register) through "your account" then "change your account status".
I just downloaded 4 albums, cancelled the subscription and thanks very much

PS don't bother using their software, and you can download single tracks only. I found it even better
