Look everyone a living example of an Apple Fanboy.
I think google and Amazon know that the RIAA can not really touch them on how they are currently doing it. Space is cheaper then more than likely what RIAA was demanding in fees. RIAA business model is very out dated and they are still struggling to stay relevant in today's internet world.
Google and Amazon are like to suffer consequences because of their rush to get out ahead of Apple. Apple took their time and did it their way, and it will likely work out well for them.
This is why when people blab about competition and Apple it is funny. Apple does their own thing and proceeds as planned. They did not rush things because of Google and Amazon jumping the gun... I suspect this will be to their benefit in the long time.
In fact it is likely Amazon and Google played right into Apple's hands. The record labels have wanted to remove Apple's stranglehold on the digital music market for a while. By jumping the gun, though, Amazon and Google have pretty much tied the hands of the record labels and given Apple a huge advantage.
It is likely that Apple took advantage of the opportunity on this to come up with some exclusive parts of the puzzle at least in the short term, which will cause Amazon and Google to fall a bit behind.
