MSN Spaces and Streaming Audio.

Ok, you might have seen how in Spaces, the place in MSN where you can
put info, pics and even a blog, you can also have music in the background, like
in some websites... here it is dome via a PowerToy for media player, but to play a song,
the powertoy asks you for the song URL,
ok, for this, Im guessing I need to have my song hosted, just like in imageshack for pics.
am I right?
if so, do you know of a place like this, but for music files?

I personally use hxxp://ripway.com.
So far so good, but there's a limit. you can uploud files only up to 30MB
