My album will never never never be on Apple. And it will never be for sale... You can only get it on Tidal. — KANYE WEST (@kanyewest) February 15, 2016

To buy a copy, you'll need to go through Kanye's website. Notably, there's been no indication that the album will be sold through iTunes, Google Play Music and other digital stores at a later date. So if you manage a personal library through either iTunes or Play Music, your best bet is to buy the tracks and import them manually. It's also unclear if The Life of Pablo will ever get a physical release -- we wouldn't count on it, although as with anything related to Kanye, it's never outside the realm of possibility.
