Amazon Prime Music
1. Given my listening habits, the library feels limited. Tried searches for the three albums I listened to the most this month (http://www.last.fm/user/labibrahman/charts):  Sylvan Esso - Sylvan Esso
  Chet Faker - Built on Glass
  Tycho - Awake

None are available for streaming. For a standalone service, this would be damning. As one of the perks offered with Prime this has the potential to become a compelling part of the package.2. Amazon's store interface is not well suited for consuming media. I tried watching a few episodes of Friday Night Lights on the service instead of Netflix. Spoilers in episode descriptions meant that I had to very specifically control where I let my eyes over the UI. Next episodes don't auto play. Perhaps most annoyingly, there isn't a standalone URL I could go to for my streaming needs. To watch an episode I had to carry out the following steps:  Navigate to amazon.com
  Search for Friday Night Lights
  Skim the results to click on the TV show
  Remember what season I was on
  Skim the episode descriptions while avoiding spoilers
  Click to stream, and make sure I don't accidentally click
  on the 1-click buy button which is annoyingly right next
  to the stream button.

My flow on Netflix:  Navigate to netflix.com
  Click on the continue watching pane on top left corner of my screen.

I want Amazon to be a legitimate competitor in the space, but running everything through the store interface is killing any chance of me using Prime as a media consumption service.3. I suspect that this works many orders of magnitude better on the Kindle Fire line of devices and that's great for people who already own Kindle Fires. If I don't already own one though, the Prime ecosystem should be driving to make that purchase and right now it is failing at that task.
