So I'm wondering if this will become a problem for kids of the future. Loading up their ipods with hours and hours of a particular style, then getting bored with it. I like having an appreciation for particular authors.
It already happens with us.
As a 17 year old who listens to about seven hours of music a day and has a subscription to Rhapsody, an unlimited music service, I switch genre about every month. With Rhapsody, (Well this is sounding like an advertisement) I don't have pay wall barrier that a lot of kids have and don't require friends to buy and expose them to new music (Same could be said to some degree for pirates.) and that frees things up enough that I get so overdosed with music that I transition the moment something get's "boring".
Yes, I'm completely spoiled that I can't enjoy a genre of music for more than a month, but a year later, I'll be coming back to that genre after doing a 360 around the music world only to find new artist and new releases to enjoy. Some things stick, even if you move on. And now with software giving us perfect recall of what you listened to a year ago, you can come back to an artist that you like a lot.
It's not as bad as you think it might be.
