Which means that you can play it loud, even on radio or cheap systems... A recording with a huge dynamic range, typically a classical recording, can also be played loud of course, but you'll most likely fry your speakers (or drain your amp) if you crank up the volume during the quiet parts...

Recordings with a huge dynamic range are more "fun" to listen to (for me anyway), but they'll be perceived as "relatively quiet" recordings by the masses, and therefore they'll think it doesn't sound good, hence the ranting about compressed music on HA...
