Making Playlists on PSP?

I have been pondering over this for quite a long time. Finally m amazed at how easy it is to do this.

1. Open your PSP memory via USB with ur PC.
2. Go to the PSP folder, open it and click on MUSIC Folder.
3. Create a new folder under music, give it any name you want.
4. The new folder is the playlist, put your songs in the folder.
5. but you need to group your songs according to the playlist and you can have as many folders/playlists as you want.
6. BUT this can only work on Firmware 2.80 or higher.
