Soundcloud announced as part of their soundcloud lab, integration with webdocs - an online document storage facility where pictures and sounds can be imported and hosted and then made into transferrable widgets like the one shown above.
As well as being embeddable on other platforms like tumblr, blogger or you own webspace, it also features neat little app integration such as the twitter one above, or a countdown timer to your next gig.
