[dba-Tech] Study of Music Reveals that It Does All Sound the Same

This from slashdot, citing an article in The Economist::

*"A study of music from the '50 to the
present<http://www.economist.com/blogs/babbage/2012/07/science-music>
using
the Million Song Dataset has concluded that modern music has less variation
than older music and songs today are, on average, 9dB louder than 50 years
ago. Almost all music uses just 10 chords, but the way these are used
together has changed, leading to fewer types of transitions being
used<http://www.nature.com/srep/2012/120726/srep00521/full/srep00521.html>.
Variation in timbre has also reduced over the past decades."*
