^^ This wouldn't really work would it? My shuffle won't play when its getting USB power, it just charges. So wouldn't it just charge not play music? I'm thinking of making something similar but with a 3volt out instead of regular USB 5volt. Reason being is that thats how the battery pack for the shuffle works. I'm thinking if I make a 3volt USB port and wire it into my car I could have my shuffle play endlessly. Not that I'll ever need more than the 12 hours it can do anyway.
