Or just simply use software like Cocktail or TinkerTool to enable hidden folders and simply take the music from iPod/iTunes/Music. Most of the meta data will be intact. If your music is all purchased, iTunes can transfer purchases from the iPod onto the computer.
My old laptop just died this past week, so I ordered a Macbook.
My worry is that upon plugging in the iPod, iTunes will recognize it and erase the files/music. If I erase Senuti and then plug in my iPod, will I have this issue?
