So I transferred my iTunes library to my new computer, but it didn't transfer some stuff that I know damn well I bought on iTunes. I went into my "Purchase" history where you can re-download things if needed, but the artists are not listed in there, even though when I went to purchase them again, iTunes tells me I already bought them and can get them redownloaded in purchase history. I looked at both tabs - "all" and "not purchased on this computer". iTunes will not let me purchase them again, either. Any suggestions?
