Alternative to Pandora radio site?

Hi Folks,

I was registered with Pandora.com site, which is an online radio music site where you enter a song or artist name and they played the music and similar music ... but it's USA based and they changed so's us Canadians can't access it anymore ... so my question is, does anyone know of another similar music site available and accessible to us Canucks? I really enjoyed Pandora site and hearing the music and artists I enjoyed as well as being exposed to other artists and music I'd never heard ... I'd like to be able to ejoy again

Thanks.
