So like many people I have (had) a very unorganized iTunes folder. I decided it was time to basically put all my files in the same format and add a bunch of the missing information to the files, most notably the artist name. I have always saved my files in the following format: Artist name - song name .mp3. then I would just add the files into itunes and of course it would not add any info into the artist field for those songs. Through windows explorer, I added artist names to all of my files and changed some of the file names but how do I go about updating iTunes to reflect these changes?
