I subscribed to Soundcloud to check it out and it's certainly very easy to use. However, I was disappointed when I loaded up my first file as it was attenuated in some way, i.e. lost about 10%/15% of its volume. I don't know why they did that and I never expected files would be interfered with, as it were.
So, for sharing music in the future I'm going to continue with what I've always done: post a link to the music file loaded up to my own web space.
