Media has much more potential
Object based/Flexible media
@cubicgarden | https://www.bbc.co.uk/rd/object-based-media
Media + Metadata = Objects
The idea behind object-based media is that you take all the assets
for a given TV or radio show  the video clips, the accompanying
audio, any music soundtrack, and extras like subtitles and sign
language translations
wrap it up in useful metadata and then use software to remix it
as needed

@cubicgarden | https://pxhere.com/en/photo/173599 | https://theprodigy.info/discography/official/experience/
Moby credited Experience with changing his perception about
dance albums; previously he felt that "dance albums had always
failed [...] because they didn't work over the full length of the
record.
Mostly they were singles collections which was exactly what I didn't
want to do," and noted that Experience "impressed me because
