I download songs straight to my iPhone. Seems great. But I want to get rid of some. I have read people say "Just check the ones you want in iTunes." But they're not iTunes...they're on my phone. And they don't seem to be able to get TO iTunes. Seems like this should be very easy (I can't imagine this medium would have taken over if this is really this difficult), so I am surely I am completely missing the simplest thing. Thanks in advance!
