I don't know. A few years ago, something like Pandora was seen as very appealing (even though I always used Rhapsody back then, so I always thought Pandora was pointless

) but a lot of its appeal has ended up with the rise of Spotify.
So if this service is going to be like another Pandora, I don't think it'll work that well. Pandora is still here because of fanbase over the years, but ultimately people want control. Maybe they didn't know Rhapsody before so they turned to Pandora, but now that they know about Spotify, they might not see the appeal in this. Once you know a way to have more control over something, you never want to give it back.
