Sorry I m kidda new to this kind of phone. and I didn't know that the phone doesn't allow you to create playlist within the phone itself. However I do know that you can create playlist with media go. But my question is that. How can you bring the playlist from media go into the Xperia X10? I create a new playlist using media go, but it only stays on library, and when I transfer whole playlist music into Xperia. only musics are transfer.. not the playlist.
