Their iOS app seems to be a much better experience than the web site, where I kept getting accidentally shunted to the "digital music" department where the prime music wasn't highlighted.

The Windows Desktop app is much better as it's all in one place (like the iOS app). However you still have to "add" the music to play it.

The Amazon store UI is poorly suited for this task.

Additionally, the player URL (http://cloudplayer.amazon.com) prompts me to install Flash, something I've been unwilling to do for years now.

I can't believe they launched something this big with that UI. If they had an app comparable to that of Spotify on mobile and desktop, so many people would have jumped right on it.

You'd think "useful search" would be a vital part of the Amazon website but look how terrible search is.

"Sort by price, please, Amazon." "Sure, here's a $10 item and a $5 item and a $50 item! Yay sorting!"

>I have to leave the player to find music to listen to?

You don't. cloudplayer.amazon.com -> type in search -> look at right-hand side.

Nope. This is also a disaster. I typed "daft punk" into that box. Daft Punk has four full albums available for prime music. None of those albums are in the search results. Instead I get a "Daft Punk's Top So..." playlist, and "Hot, Sweaty Summ..." playlist, and "Janelle Monáe and Mo..." playlist.

I can't fault free new music, but this interface feels like it was poorly bolted on to a retail sales website, which is exactly how the web video service has always felt.

Edit: I just realized that 3 of the albums are in the search results. I turns out the right tab is scrollable, and after 15 items, it switches to showing matching albums, which includes 3 of the 4 Daft Punk albums, and also some Macklemore.

I didn't notice this because nothing I was looking for ever actually showed up there (even though it is available through Prime Music).
