The passive/active experience angle is an interesting way to look at it. I wrote the blog post, but obviously I'm a music lover who usually consumes in a very proactive way, always looking for new music. But I still think the passive experience type of listener is actually more likely to fall for the subscription/cloud model, in that it's so much more convenient than downloading. The 10 or so seconds it takes to actually download the song and sync into iTunes is going to be more and more unacceptable for the younger and younger kids.
