When the complete playlist fits in the mpeg buffer, and
the playlist is played multiple times, the tracks are
reloaded from disk multiple times instead of loaded only
once.

From an examination of the mpeg code it appears that
when all tracks in a playlist can fit in the mpeg
buffer, it is filled with as many copies of the playlist
tracks as will fit into the mpeg buffer, and when the
low water mark is reached, the full mpeg buffer is again
loaded from the disk with multiple copies of the
playlist tracks.

It would be desirable to detect when the entire playlist
fits in the mpeg buffer and only load one copy of the
tracks once and then play them repeatedly. This would
decrease battery drain caused by the unnecessary disk
accesses.

This situation is easily demonstrated by playing a short
track (smaller than the mpeg buffer) and selecting
“Playback→Repeat→One”.
