This can be useful for use cases such as games that use many long background tracks, which are all downloaded before the game starts. Using Web Audio would cause huge memory footprint as all tracks get fully decoded after downloading. Using HTML5 streaming avoids that, but didn't allow to fully download the file beforehand, which now can be done by setting `preload` property to `full`.
