Here's the mobile version of yesterday's Spotify prototype, and some of the decisions behind it. The album waits in the mini player, because that's where you are when you start a podcast. The card peeking out is too small to tap, so the album's artwork in the mini player is the button. Only one thing moves at a time. Two covers flying past each other looked messy. When the album comes back, it lifts clear of the podcast first, like pulling a card from a deck. The audio crossfades and picks up from the last second you heard.
