Wow. This is outstanding. Amazon is solidly developing a one-stop centralized base of entertainment. Even more enticing is that it's <i>free</i> with prime, and even if you don't have prime, it's worth getting prime for: a small fee for a year's access to most music/films you could want. And then you have prime, which makes it much more enticing to buy products on Amazon (due to cheaper, faster delivery). Smart.<p>(I am aware that Amazon's music library is currently not as large as that of its competitors. I think it is reasonable to assume that this will change in the near future.)<p>The more significant thing to note here is that the general trend in online businesses (obvious examples will include Google, Apple, and Facebook) is that every business is trying to create its own walled garden --- they try to provide all the services that any user could need, such that the user would not do business with any competitors, and so the user would interface with the business as much as possible. Apple did a remarkably good job at this with iTunes back in the day --- they were the first to provide access to a massive online store of entertainment and to integrate it very heavily with their products.<p>Amazon, however, is taking the cake in this respect. Their products are extremely well-integrated: www.amazon.com is gradually becoming a one-stop-destination for most media and for general shopping. Perhaps this is due to Amazon's perseverance: I've never seen Amazon weaken its hold on a particular share of any market.
