My digital music collection should have been my pride and joy. After downloading and sharing with my friends I had accumulated over 250 GB of music on my hard drive. The problem was that when I uploaded this music into my iTunes library it became almost unusable. My music had come from so many different sources that there was duplicates of individual tracks. Many of the songs had missing information and were just displayed as “unknown track” by “unknown artist”. What a nightmare!When you have a lot of missing information in iTunes it makes searching for songs very difficult. Imagine you want to listen to “Smells Like Teen Spirit” by Nirvana. So you type “Nirvana” in your iTunes search box. When nothing shows up you know that when you ripped your CD onto your iTunes there was a problem with the track information. By default the arti toro lawn mowers st would have been categorized as “unknown artist”. You know the track is from the album “Nevermind” so now you try searching for this instead. This time you get 12 results that say “unknown track” from the album “Nevermind.” So it looks like some of the track information is there but it is incomplete. You now have to listen to each track individually until you discover which one is the track you are after. What a headache!Duplicate tracks are equally if not more annoying than missing information. In theory you should just read through your iTunes library and delete anything you see twice. If you sort the track names alphabetically this should be straightforward. The problem is that in most cases there is misspelt, inaccurate or missing information so it is very difficult to ascertain whether you have identified a duplicate or not.
