I wonder how much this UI mistake is costing Spotify?

So here I am listening to some music on Spotify. This is a great album. Maybe I’ll buy it – I wonder how much it costs?

I’ll hit “buy album” to find out…

“Sign in to purchase music”. Well that sounds ominous – I don’t know what’s going to happen if I enter my password. I still don’t know how much the album will cost, and since I’ve entered my credit card details before, they probably have them on file. Will my card get instantly billed an undisclosed amount?

You can bet that the vast majority of users are going to err on the side of caution and click “cancel” at this point. I’d love to find out what kind of revenue uplift they’ll get when they fix this issue. It could be Spotify’s very own equivalent of the $300 million button.

Thanks to @delarge for pointing this out.
