Okay, I figured out how to get it to scrobble to the right page, at least in iTunes, if it's going to the wrong page. Go to any WitTR music you have, show the info/metadata, completely erase the artist and album artist information and save it. Then show the info again, and retype JUST the artist information, word for word, and override any autofill. After that it should scrobble to the right page. It did for me. Not a clue why it works.
