I will offer this analogy: regular music is like a healthy person and Muzak a like a zombie creating virus.
Not does only Muzak stink like rotting flesh (for your ear lobes that is), it is infectious and can only be removed from your brain by a bullet. There is no cure, only prevention.
Anyway, seems like when a musak-ized song doesn't sound Kenny G. or Anya, it sounds like that violin part from that song "Come On Eileen".
Weird, huh?
