Hi, I've installed iTunes on 2 PCs. The 'library' and all playlists were created and exist on the first PC. I recently acquired a laptop. I installed iTunes on it and purchased a number of songs. I have a playlist on the iPod that was created on the first PC. I'd like to add the newly purchased songs to this playlist. The playlist is not visible on the laptop from the iPod. Is this possible or does a playlist have to reside and be updated on only one computer? Thanks!
