I'd say it's worth around $19 (say, if it were to be sold on eBay...) until it is developed further or until you find an end user. I agree with the previous poster that this is a tough one to monetize for resellers. Huge competition, and the players in this arena, were they to spend good money on a domain, probably wouldn't settle for .us - at least right now. I'd say your best bet is to market it to bands or musicians. Good luck!
