I have 29 annoying music files in my iTunes download section that have the message "Download error. Tap to retry". They do not download despite various fixes, such as turning off cloud, rebooting, turning off auto download. The files are part of a large set of nature sounds I wish I had never downloaded.How do I get these out of my ITunes download cue? Thanks. BTW, I have read all other posts I could find and non of the fixes worked.
