Hello, I have been using the iPodTouch and Mac for years. I bought the Galaxy Note few days ago. I connected my Galaxy Note to the Mac using an USB cable. Then, I used doubleTwrist to copy the music files to the Note. After the transfer, my music files got all messed up when displayed on the Note. (Perhaps I did not do a good job in organizing the files under iTunes right at the beginning.) I want to do a fresh start. Could you please let me know the following: 1. What is the best way to delete all the music files from my Note? There are hundreds of them. I do want to keep the good music files originally installed by Samsung. 2. Is doubleTwrist actually the best app to transfer music files from the Mac to the Note? What other suggestions do you have? 3. In order to avoid messing up the files again, should I just copy the playlist from iTunes to the Note alone? I am not familiar with iTunes also. Any advice appreciated. Thanks.
