TasteKid

You've got good TasteKid.

There's not much to say about this website because there aren't a lot of features. But the feature that it does have is really amazing. TasteKid is an extremely comprehensive band, book, and movie recommender.

That's exactly what it does - it recommends things.

Based on the band names, books, or movies you enter, Emmy (the kid who has good taste) tells you what you might and probably will like. You type in a few bands and it gives you a few dozen. And if you search a book or movie, it cross-recommends to give you answers for all three categories (and sometimes even TV shows).
What's really exciting about TasteKid is that its recommendations are exactly what you would want them to be. It's as if you had asked a close friend to recommend you something.
