Hey guys, i have been messing around with ttr, and noticed that not all of my itunes library comes up when i click itunes library. there are a few artists that are missing. For example, i made a metallica master of puppets tap earlier today, but when i went to itunes, metallica did not even show up. Why is this? Is there any way to fix it? (i have wifi by the way if that means anything) Thanks for the help!
