Why apple doesn't sell preloaded iPods

"Other recommendations for you... by Apple"

When I checked out an iPod, I didn't see any option to preload it.

Wouldn't that be a great value add. It would also help if they can get discounts on preloaded albums. Maybe they should start -

1. 'Bryan Adams iPod Shuffle' - Has all the albums of Bryan adams
2. 'U2 iPod' - all the albums of U2
3. 'Jazz iPod' - top 100 Jazz music songs
4. .... etc
   

This would add to the emotional impact on the user experience. Family orbit of AIEUO !!
