Sirius radio song tagging on nex4000 doesent seem to work.  When I tag a song it tells me I have 49 or 48 left etc.  Song does not seem to go anywhere on my iphone or itunes. Tagging also only seems to show up when I am not conneted through usb.  Not sure if I have something set up wrong.  I don't listen to regular radio so not sure if it works there.
