Basically this is a voucher I got from a dude on ebay - its a transferable evoucher that gives the holder 35 downloads from emusic.com.

To get the most out of it:
i) sign up for free trial
ii) download 35 tracks
iii) cancel free trial

From experience you will need a CC to sign up with, but cancelling before the 14 day trial is up means your card is not charged - not a cent - and the tracks are yours to keep. No DRM on tracks, which is niiiice.

i hope this is useful to you, just spreading the love!!
