Most people still have no idea what Tidal is, but that's likely to change if Jay Z continues playing his cards right. See, the music mogul has just convinced Taylor Swift to give the Norwegian hi-fi streaming service -- that he snapped up -- the right to stream most of her albums. As she's one of the world's best-selling artists, she certainly has the following to help spread the word about the company. But doesn't Taylor dislike streaming services? Well, not exactly. She left Spotify last year, because she wasn't happy with its free, ad-supported tier -- on the other hand, she stayed with Rhapsody and Beats Music, because they don't have a free option.
