The whole concept of Wii music falls within the realms of the PS3s and the Cell processors greatest strengths. To be honest there is no better platform on the market today to implement this game properly than the PS3. Im not saying that the Wii doesn't do it the right way, but compared to how far the PS3 could take this concept it would look wrong by comparison.
Interface
Take your hands off the mouse and keyboard and point them at the screen. Conduct an orchestra, play air guitar or pretend you're playing the drums and you'll understand the concept. So take one or two cameras, one fast processor and free your hands to express yourself while in the background billions of floating point calculations are conducted to analyse your movements precisely and convert it into music. Essentially take eye toy to the next level and really push the boundaries of how we humans interface with a machine. Think of your whole body as a tool for expressing yourself musically.
Expression and learning
How many instruments you want to learn how to play? There are 50gbs of space for all the instruction videos you could ever want to play. But how about they take the concept of not being able to mess up the note to a whole new level? Take that electric guitar that you've always been meaning to learn how to play, plug it in and have the PS3 intercept the signal from the guitar so that you can focus on learning one aspect at a time such as strumming, whilst not sounding like a complete douche to yourself and others and build up your confidence and skill without overwhelming the novice player. You can save your progress to disk, share it with friends over PSN or keep it to yourself. The possibilities for networking and creativity are endless.
This whole concept could apply to any instrument, play a flute, piano, violin and have the game give you instant feedback as to how you're doing it right or wrong. Whats the biggest issue with learning an instrument? Its learning how to learn an instrument and overcoming the first hurdles where most people give up frustrated after they feel they made little progress.
Give a man a fish
The concept of play. The fundamental driving force behind 'play' is learning, experience and social interaction. The concept of play is something that humans have in common with most of the other mammal species. Bounce a ball against the wall - once you learn how to catch it, it becomes boring. Bounce that same ball with a friend and it becomes sociable. Join with a few of your friends and play tag with it, and it becomes a physical experience/exercise as well as being social. Notice the trend in terms of how fun each possibility is with a ball? The issue with Wii Music is that it never goes beyond stage 2 and it never lets the player pick up the ball and run with it. Wii music is a sterile concept because of this.
Take it to the next level
Express yourself with your body, pick up a couple of pens and play drums, plug a guitar into the PS3 and play through your TV, pick up the singstar microphone and sing yourself tone deaf or learn how to hum the bars, jam with your friend in New Zealand who has a Kirk avatar or drag your family into the lounge for a family jam session. Its up to you.
I'll leave it there - so whats your take? What colour is my ganja smoke? 
Tease.
