I can't use it either; sadly they are only open to the US. But I checked out the site Steven linked (plug.dj), it's open internationally. They use YouTube and Soundcloud for music/videos so you can play almost every song you want. For now you need Facebook, Twitter or Google+ to sign up but I heard a email sign up function is in the making.
And if you really want to try it out you could consider make an anonymous Twitter account to sign in with.
