I'm using the latest firmware on my iPod (with the gapless playback) and I noticed that while a song is playing, navigation (scrolling through artists or selecting things) is really sluggish or laggy (for the lack of better words). I don't remember the iPod doing this before I upgraded to the newest firmware. It's too bad because it used to be silky smooth when scrolling through songs even if a song was playing. My other problem is. I turned on "Display Album Artwork on your iPod" and for some strange reason, it still doesn't show the Album art (Even though most of my songs have art attached to them).
