With all that hype surrounding it, it is easy to overlook a very simple reason that makes a service like iTunes so attractive.
iTunes is a Time Machine.
I spent a few hours (and dollars) going over their catalog, looking for particular albums and as I was coming across some unexpected titles, it hit me – there are so many songs I used to like and listen to years ago but never bothered buying because they were burried into albums with other titles I couldn�t care less about.
Now here they are, potentially available with a few clicks of a mouse. iTunes catalog may be limited (where are all those french artists I would love to listen to ?), but it already contains plenty of titles to make up for lost time.
