Plus the genre's are rather limited, it's usually one or two pop stations (with 90% song overlap), one or two country, maybe NPR or something in a podcast format, etc. Meanwhile all of the ads.
Personally I'm on the student plan, and for what I like the listen to it's a steal for 5$ (and free hulu?) Any of the alternatives, deezer, apple music, etc would likely work too, but I can't imagine only using fm radio stations.
