It could, but it doesn't. Look at the mp3 thread debug screen and you'll see that we have a huge margin (>128KB). This added spinup time should not affect us negatively.

Further ahead, we will implement a dynamic watermark handler which will adjust itself to the speed of the disk and the playing bitrate.
