"Each year we try to incorporate features that allow you to customize our MLB THE SHOW franchise to your specifications. Making a soundtrack to satisfy all players, from all walks of life, is nearly impossible. So, in an effort to please all fans of the MLB THE SHOW franchise, we are offering the new My MLB Music feature. My MLB Music will allow you to take the music you have on your PLAYSTATION 3 Hard Drive or on your PSP Memory Stick Pro Duo and create your own Jukebox Playlist. From the Jukebox screen below, just press the circle button to activate the My MLB Music feature.
Hope you enjoy MLB 08 THE SHOW and the My MLB Music feature when the game launches March 4th. In the meantime, try your hand at the MLB 08 THE SHOW demos, hitting the PLAYSTATION Store for PS3 AND PSP this Thursday!"
