Instructions
Getting Project Playlist Music
Install Firefox if you aren't already browsing the Internet with it.
Install the DownloadHelper plugin for Firefox. Restart the browser for it to take effect.
Open your playlist from Project Playlist. Notice the new icon on your toolbar that begins to animate--this means it detects media that may be downloaded.
Click the animated icon. A list should drop down of embedded media on your active tab. Click the song you want to download for your PSP. Do this for each song you want.
Wait for the downloads to finish. If you chose multiple songs, this may take several minutes.
Transferring to PSP
Connect your PSP to the computer.
Make sure your PSP is in USB mode. If it is not, navigate to "USB Connection" located under "Settings" in the main menu. This will enable USB mode.
Open the drive on your computer. A balloon notification should pop up and let you know your PSP has been successfully connected, which means you can see it in "My Computer."
Open the folder where you downloaded your music in another window.
Select all of your downloaded music. For multiple files, use the "Ctrl" key and click each file. Drag them into your PSP folder.
