Retail giant to burn discs on demand.

Wal-Mart has introduced an online custom CD burning service that allows customers to buy tracks without downloading them to a computer.

Users select and buy the tracks they want, which Wal-Mart will then burn to a personalized CD. The service charges $4.62 for the first three songs, and 88 cents for each additional song, plus $1.97 for shipping. Based on those fees, a 14-track CD would cost $16.27.

The new service is positioned for consumers who do not have CD burners or broadband Internet access, but who still want to take advantage of the flexibility that digital music provides.
