Using a database of 400 different aspects of descriptions of music, it matches up music in their files with the artist or song you’ve chosen as the seed for your station. The consistency is impressive.
But that’s also the drawback.
You’ll be introduced to new artists, certainly (it’s how I discovered the chewy goodness of Maggi, Pierce and E.J. But since every song is carefully chosen to match existing criteria, you won’t stumble across gems which are fundamentally different from what you’re already listening to.
I keep making new stations (you can have as many as you want) and seeing how far I can stretch it before it breaks. From the perspective of “if you like X, you’ll probably like Y” I haven’t found anything better.
