rharv,

There's various cost levels. I'm trying the free version which allows up to 5 uploads a month for a maximum of 10 tracks at a time. I like the play tally and the ability to comment at a particular location on other folks tracks.

Also, supposedly there's player widget that you can imbed on other sites that gives a smaller version of the waveform thing. I haven't tried that yet - though that's how I first found out about it - clicking on another person's track on their blog post.
