A:Answer Thank you for your interest in the Lifestyle 600 home entertainment system, Mike! This model is not engineered to physically store music on a hard drive, however, you can access your entire iTunes collection by streaming it over Wi-Fi to the system. Your CDs can be copied to your iTunes account, and then the music can be accessed with our free SoundTouch app. The built-in Soundtouch service can access thousands of songs through services like Spotify and Pandora as well. Hope this helps! Jesse - Bose Support
