It's still a little spotty, because album sales are entirely up to the artists, and many of them haven't turned on the feature yet.

Plus, it takes a little bit of setup on their part - they need a Stripe account to accept the payments, then link those payments to the albums (and digital downloads) that they're selling.

But once that's done, it's pretty seamless.
