I was able to get onto this even though i'm not in any of the countries its freely available. Just went to this
https://www.spotify.com/en/get-started/ page through a proxy, which i found here,
here or
here the countries its free in are UK, Finland, Sweden, Norway, Spain and France. So look for a proxy from anyone of them countries.
Used ie7pro to switch proxy(
here's how), which probably wasnt necessary, but its an essential add on for anyone using ie7 anyway if you use ie7 and it just makes switching from proxy to proxy easier.
Might take a few different goes, spotify seems to be able to weed out certain proxies.
Oh and you'll need to be able to find a postcode from whatever countries proxy you get through on, its only a simple google though.
