A new music kiosk allows customers to mix their own CDs, choosing from 200,000 songs. “At $10 for the first seven songs and $1 per song after that, it’s not as cheap as free, but it is legal. And the service addresses a fundamental problem with how the music industry sells its product: People don’t like paying $15 for a 10-song album when they want only two of the tracks. The company hopes to expand the concept to digital movies, games and software.”
