On Bandcamp, the listening statistics for each track are broken into three categories: completed, skipped, and, curiously enough, partial.
Youtube has a section on one’s homepage that is labeled “Continue Watching”.
Pandora features a skip feature. Alas, it is limited to a certain number within the hour due to music licenses.
Skimming is a feature of today’s music landscape. One can lament over short attention spans. It is has already been done.
What implications that skimming has on listening and performing and archiving and presenting music? Why, that is a conversation worth having.
