Instructions
Download the correct music formats. The PSP can play music only in MP3, AAC and ATRAC formats.
Insert the Memory Stick DUO into the PSP's memory card slot. The PSP has little internal memory. To download music files, you should insert the Memory Stick DUO into the card slot on the left side of the device.
Switch the PSP to USB mode. To download music from a computer, the device must be in USB mode. Connect the PSP to a computer using its USB cord. Turn on the PSP and select "Settings," then choose "USB Connection."
Create a "Music" folder on the Memory Stick DUO. With the PSP connected to a computer through its USB cable, click on the desktop "Start" button and select the "Computer" or "My Computer" folder. Double-click to open the PSP drive folder. Right-click in an empty space within the PSP drive folder and select "New" and "Folder." Rename the new folder "Music." Drag compatible music files on your computer into the "Music" folder.
