I like media of all sorts that matches my mood. If I'm sad, I don't listen to music that cheers me up, I'll listen to the saddest stuff I can find. But this app's approach is really geared towards managing your mood, so it'll try to make you happy. Or if you're confused, it suggests books to improve decision-making. And if you're energized, it suggests you use that energy reading about running and getting healthy.
Again, that's not a bad thing! Just a viewpoint that's embedded in the suggestions. Those choices are explained nicely, so people can decide if that's what they want.
