squeezebox music

hi,

i have bought a squeezebox 3 and i am impressed with it so far but the only downside is that rhapsody and pandora are the companies that are available with the sb3 but they are only available in the u.s.

does anybody know of any sites that i can join for music on demand that is similar to rhapsody either it being free to stream or subscription and pref with flac formats.

                       thanks in advance neil.
