With the invention of M4As and AAC (Apple's primary codecs for music) we can see a huge increase in bitrate quality digitally. This is tremendous news because iTunes(r) is a registered software to Apple, Inc. and is able to render these requests via an Apache server to ensure a download request is fulfilled. These are not P2P programs (peer to peer), merely a Server to Peer (P2S) iP2 Apache request. This is very significant because we can see people such as Steve Jobs inventing the iPad and creating multiple new technology really increase on the stock market.
While 256kbps seems great, 320kbps on an MP3 is the best. We really need to start pressuring the new music artists to use 320kbps on their CDs they are coming out this fall!
