I have a Samsung Captivate, with Froyo, and love it.
However, when I connect the phone to my Mac, via the mass storage option, and then try to drag mp3 files or folders from my computer to the Music folder, (which has lots of mp3 files, and they work well) I often get a message that there is an error with the mp3 file, and so it won't copy.
I suspect that this may relate to mp3 tags, but the same files work fine on my computer. All of the files that did copy successfully to the Android work fine. Any idea how to get around this, and copy any mp3 files to my Android?
