This will greatly simplify the hobby that many chavs seem to be taking part in; the aggrivation of fellow passengers on public transport by playing low quality music through low quality speakers on their cheap Nokia handsets.

"Plus, instead of using MP3 as the file format, it utilises EACC which is eight times faster to download. And you can store eight times as many tracks."

I guess you mean EAAC (HE-AAC), but still 'eight times' compression over mp3 is total BS, if you want comparable quality. If Nokia generally uses 192 kbps quality MP3:s, it would imply 24 kbps HE-AAC quality. Which is enough to even make most untrained ears bleed. Even though HE-AAC is more efficient at very low bitrates than MP3, you are still not going to pass (say) 80 kbps MP3 quality with 24 kbps.
