There are four songs on Humalien and the whole EP can be purchased for $4 exclusively at Treasure Craft Records. You can also find the 10-inch vinyl version at the same place for $10 which unlocks the .wav file versions via digital download. Pretty sweet deal, but but you might want to hurry beacuase vinyl is limited in stock. Of course, if you want to hear more earthlings? you can click on the iTunes logo at the top right of the page.
