Rdio has introduced an updated Stations feature. You can now create a station off any artist, song, genre or user. I really like that it has a slider that runs from base-->adventurous. I've always found it annoying that if you put a Canadian artist into something like Pandora, all you get back is the same 10 canadian artists, instead of the music type from all regions. The slider seems to be pretty good at branching the selection out a bit. When you're listening to the station of a user, the slider keeps the selection either totally within their collection or it begins to stray to similar stuff.
It's turning out to be a great discovery tool.
