This should be a simple one: In iTunes I manage my music manually. Sometimes I need to change a song's file name because something was spelled incorrectly. To change a song's file name I rename it in Finder. iTunes is running the background. Now here's the catch: After renaming a file I check whether iTunes detected its new location (CMD+I for "Get Info"). Mostly iTunes DOES recognize the new file path, but sometimes it doesn't. What helps iTunes detecting the new location? I really can't see a pattern in iTunes' behavior. Thanks in advance.
