Here is why Genius is the perfect feature for Apple to release at this time

Apple is great at following the trends of their customers.  The iPod, despite not being the first mp3 player, really did revolutionize the way people listened to music.  As they saw their users becoming interested in videos and podcasts, they shifted and adjusted their products and software. It’s what they do.  One trend that has developed since the dawn of the iPod and iTunes is that people’s music libraries have grown and grown.  Many users have gigs and gigs of music.  I’ve heard people brag about how many days [or even weeks] worth of music they have in their collection.  This is a good thing, dot get me wrong.  I’m a proponent of people loving and having tons of music, but it presents a problem. You cant want to listen to every type of music at the same type.  Shuffle becomes useless.

How do you organize all of this music so that you can hear what you want when you want?

Well users are inherently lazy.  Some users will create playlists, some will organize their music meticulously and have only their favorite files prepared for playback, but most users will shuffle their iPods and constantly skip the sings they don’t like.  I, not too long ago, removed near 80% of my music from my library to stop hearing the songs I like but don’t want to hear all the time from popping up when I put my iPod or iTunes on shuffle.

Apple’s Genius solves this problem beautifully.

By combining the data they have mined from the mp3 sales in their music store and the data you have provided in you library they can dynamically generate a playlist of your own music that matches the style, tone, and feel of a song you select.  Think of it as Pandora with your own music library.

This means that users can have the playlist they need with minimal work.  Now you don’t have to feel like you need to limit your library because you know you can always get that perfect playlist at the click of a button.

Genius.

UPDATE:  I’d like to add that not only did they solve this problem, but they did it in a way the places ads for new songs in front of your eyes.  Very clever Steve.
