I bought and copied Taylor Swift's second and third CDs "Fearless" and "Speak Now (2-CD Deluxe Edition) and ripped them just fine onto iTunes. They also went on my iPods easily. I'm unsure about the other two but I'm sure they work normally. Good question though!
For anyone interested, I was able to "Rip" the "Red" CD to my Windows Vista PC. I did not have to do anything special to copy it (I do not use itunes).
Thanks for the feedback Adrian. Someone wrote an Amazon review on one of Taylor's CDs that said she couldn't copy it to her PC, so I was concerned. It would have been a waste of my money if I couldn't copy the music to my PC, music players, and flash drives. Thanks Taylor and Co. for not putting some sort of copy protection on it.
