I also use Soundcloud, and I think it does a great job.
I like that you can post either a link to your total Tracks or to individual tracks.
I also have a Reverbnation site which is OK, but I don't like the link from Facebook to it, and you can't link to individual tracks.
I am thinking of abandoning my MySpace site - I don't like it at all anymore - However, once, it was the only way!!
