How exactly does album discovery work better in the physical world? If I'm walking down the isle and see an album cover that has artwork I like on it, or just grab one out of the Pop/R&B section because I liked a pop song I heard on the radio, or grab an album that was recommended by a store clerk on the recommended shelf? All those are nearly just random discovery.
