Our little guy has really been excited about music over the last few months.  We've had a whole bunch of discussions about what is or is not music.  So we've watched STOMP, found some hambone solos, listened to some ambient compositions, and some harshly modern classical stuff.  Almost everything gets judged as "music".

I've been really surprised at how much he's into the atonal, non-melodic things.  The kid loves all the KidzBop stuff as well, but pretty consistently he requests "that one where it sounds like nature" (John Luther Adams - The Wind in High Places).

Anyway, what music (or not music) are you listening to?
