Soft Reset -- Bug or Hardware Problem?

First, is there supposed to be a delay before the reset when you press center and volume +? On mine, touching them even for a moment resets.

Second, there are times when pressing center to select “back to the music list” will reset rather than going back. It seems consistent, if it starts doing it, it will do so every time unless I change which album/playlist is up, or something else on it.

Is it possible that the reset has to do with the current song? But it seems to do so on many songs, most of which show up properly named.

If this sort of thing is a hardware issue it would be great to know.
