I disagree. It's pretty intuitive for me, and I've listened to music on CDs. Personal opinion vs personal opinion.
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.
