iPod nano freak-out

I have officially had my first buggy experience with my iPod nano. Yesterday, during the commute home, the person sitting next to me exclaimed, "It's so small!" as I was pulling the nano out of my backpack. I began bragging about the nano, recommending that she go buy one immediately, and began showing her all the features.... or at least, that's what I was planning on doing when the nano totally freaked out.

I was playing a song off of the new Dandy Warhols album (get it, btw; it rocks better than their last one; sounds more like Come Down, which is their best album to date, imho) when I noticed that the album artwork was only loading for every other song. Then, I tried to show her the photo features of the nano. I clicked on my photo album as she exclaimed, "It takes pictures, too?!?!" As I said, "No"—and made a mental note to myself to build a camera attachment for the nano and become rich—I noticed to my dismay that none of the pictures were loading. "That's weird," I said, as she asked if I already had pictures on it or not. The battery was on the low end, so I said that that may have had something to do with it. Then I tried to go back to listening to the Dandy Warhols, who had for some reason stopped playing. When I got back over to Currently Playing, I found the nano totally freaking out starting to play a song, then failing and jumping to the next song, so fast that there was no audio playing and the screen just kept switching rapidly between song titles. None of the controls worked. So, I had to force a reset (middle button and menu held down simultaneously for several seconds). The nano rebooted and all was well.

Anybody else out there noticed this odd sort of bugginess? Wondering if I should take mine by the Apple Store for replacement or if this is a 'normal' freak-out for flash-memory based devices...
