The confusion/misdirecting part for me is that I would expect to hold down a 'Seek' button to seek through the track. However, as a user, I was just trained to recognize the 'Seek' button as 'Next' or 'Previous' track. So there are conflicting messages in their design. Why would I want to hold down the 'Next Track' button to seek ahead in the song? I would never think to do that.
