Putting Music on your PSP
1. Connect your PSP to your computer, create a USB connection from the settings menu on your PSP.
2. Open the drive letter your computer gives your PSP.
3. Open the PSP folder, then open the Music folder and copy your music files there.
You can put your music in a folder if you want it organized.
You can't have a folder inside a folder like Artist \ Album \ track01.mp3

e.g:
x:\
\---PSP
\---MUSIC
| Track01.ac3
| Track02.mp3
| Track03.wma
|
+---Folder1
| Track01.mp3
| Track02.mp3
| Track03.mp3
|
+---Folder2
| Track01.ac3
| Track02.ac3
|
\---Folder3
