Connect your PS3 and PSP with the USB-to-Mini-USB cable. The larger USB head plugs into the PS3; the smaller head plugs into the PSP.
On your PSP, go to the "Settings" column and select "USB Connection." It now shows up on your PS3 menus as a USB device.
Navigate to the "Music" column of your PS3&'s main menu and highlight the playlist you want to copy.
Press the "Triangle" button and select "Copy" from the menu that comes up on the right side of the screen.
