title: preload html5 audio while it is playing
body: <p>For HTML5 Audio, let's say you have a list of two songs you want to play. Currently I have it set up so that when the current song stops playing, it loads the new song and plays it. I want to have it so that it loads the next song while the current song is finishing, maybe 20 seconds before the current song finishes. I tried to change the src attribute for the audio object while the song is playing, but that just immediately stops playback for the current song. Is there some other method that allows me to preload the next song while the current song is playing?</p>
