Wii Music – which "turns players' movements into great music, even if you've never picked up an instrument before" – will be released in North America on October 20. If you had a copy of Wii Music, and it had one of those sad party blowers that never really work as an instrument, you could "blow" it right now by, um, waving the Wiimote. Or maybe a slide whistle would be more apropos.
Remember: exercise caution when driving to the store right now to pre-order Wii Music. There's no need to drive all crazy; the streets will probably be jammed with people doing just that. Why wouldn't they be?
