Preloading stream audio or not?

Hello, I was just wondering about something so i thought you could tell me what you think about it in general.
Creating a mp3 player, I’m loading an external swf (around 800kb) containing only a track set on stream, on release of a button. Is it worth preloading it?
I made it try by a few friend and noone complained about the sound without preloader but what would the effect be for someone with a slow connection?
Also, would it be possible to preload the tracks in the background while the main movie is running. If yes, how would I go about it without affecting the main preloader and the main movie size.
:hangover:
I’m tired I’m off to sleep. Nighty nighty.
