Very! You have to take time to tell it what you like and don't like. I'm training it now, and I have to say... it's awesome! There isn't any country music station where I am... excelt HD-Radio... and that isn't too good. This is great. No ads, no bull, once you train it, I'm getting closer to all songs I like.
Genius. Between things like this, and Digital FM, and looking at Sirius stock... I'm thinking it's time to cut and run from Sat. Radio stocks. They just aren't going to be needed. People say they like Sat. because there aren't ads... but cable started out without ads, and that didn't last.
I don't know... but enjoy.
