I have a lot of classical and concert CDs, and the gap between songs is annoying. It would be great if a future firmware upgrade allowed gapless. It would also be nice if the Clip would play M4As (LC-AAC).
I know it’s possible through a firmware upgrade because it’s been done on Sansa models through the open source project Rockbox.
I hope the Sansa devs can look at the source and get some ideas.
