receiving electrically transcoded audio waves,
which have been compressed by at least one mathematical process,
had tons of data shed off the original sound wave curvatures,
been transmitted over at least three different transmission media,
and by at least two different types of processor,
to finally be delivered to your ears with at most 60% of the original information,
and over short range non-cable transmission,
using yet another form of compression this time with encryption,
all to reproduce what to you, sounds exactly like someone playing in the room next to you? Yep, blows my mind too.
