Right, because it'll read the first mp3 frame and treat the whole file as a
CBR using that bitrate.

What I *think* might be happening, is that the mpeg thread is tricked into
believing that this is a low-bitrate song and thus it adjusts the watermarks
a bit on the brave side to make the best use of your mmemory before it spins
up the disk, but as the song really is using a lot more bits than the mpeg
thread initially thought, it runs out of buffer before it has spun up the
disk and re-filled the buffer to keep on playing.

To say if this is likely or not, I need Linus to comment.
