Outersounds: iTunes for the Independent Artist. Help test their system

As some readers of IU will have seen, we're highly recommending Outersounds for Artists who wish to sell their Music online. Like Napster, iTunes etc, Artists sell tracks for 99c, but get to keep 88% of profits (after PayPal fees are taken out. See IU News for sample calculations).

Anyway, we're heavily involved with testing this new Indie/Unsigned Artists sales system, and, to do so, we'd like your assistance. Now, I *know* that all in here have DeXtra MP3's coming out of their ears (nice pun, eh?), but bear with us.
