At least in the digital world, there is an evolution from scarcity to abundance in many domains. This evolution creates important new opportunities and challenges for (higher) education and strongly influences the expectations of students and, increasingly, of teachers.
In the media in general and music in particular, this trend is clear. The average young person in the 70s had a collection of maybe 20 LP's, which were heard at home. The average young person now has virtually all music ever recorded at her disposal, and can listen to it anywhere and anytime, via an iPod and other devices. She can share her music with friends - legally or not.
Because of this great abundance of material and its availability anytime and anywhere, it is no longer meaningful to deal with music in the traditional way. One can manually manage the music on 20 physical carriers. This approach no longer works with 3,000,000 songs. A first workaround is to provide sophisticated search, so you can create playlists of songs by title, artist, etc. Then the playlist can be played without further intervention by the listener. That is roughly the original model of iTunes. It is also roughly the model of the teacher who searches for relevant learning resources, modifies and packages them and expects the student to work through the material in a more or less controlled way.
