Here’s an idea – Pop Swap! Two people swap record collections (OK, not the whole record collection, say 20-30 CDs each or digital equiv.) for a week AND provide ‘rules’ regarding their typical use of the music – when they listen to it, where and doing what. They try to follow the other’s rules and listen to the other’s music as much as possible and keep a blog or diary or something of the experience.
This complicated and unworkable feature idea inspired, obviously, by Wife Swap.
