movement id changing room

Hi, I'd Like to know which setup you'd recommand for someone who'd be wearing a device changing room and the music would follow from room to room crossfading?

Walkman/iPod?

Do you mean a changing room as in a room where you change for something like swimming. Or do you mean a lone person wandering round a house.
If they are the only one in the house why bother, why not have the music piped to all rooms?
