Heya,
I've been using Last.fm for quite a while but they've dropped some of their licenses so now I would have to pay to use the radio feature. So I'm looking for a new social music website that will allow me to listen to music (or parts of music) and add them to playlists so that I can discover new music and share with friends. It has to work in Australia though.
Anyone got any recommendations?

Imeem

Triple J is an alternative music station broadcast all over Australia, you can stream it live online...

triple j (http://www.abc.net.au/triplej/)

thesixtyone - a music adventure (http://www.thesixtyone.com/)

I'm not sure about Australia, but Imeem and Pandora are pretty popular in the US.

I'd say Pandora and Slacker radios are both pretty good.
