They're probably all different and all proprietary. On my CD player
(200-disc carousel), it would pick a random disc, and then choose a
random song within that disc. So I'd spend a lot more time listening to
_Thick as a Brick_ (one track) than I would listening to something from
the the first two Simon and Garfunkel CDs (2 albums and 20-some tracks
each). (I took _TaaB_ out... I don't like it _that_ much.)
MP3s don't come in albums, but it's conceivable it could choose a random
(equally weighted) folder, then a random (equally weighted) file within
that folder. Careful analysis over many hours of play or simulated play
would probably lead you to figure it out.
It could take into account the tracks' running time. If it deals well
with VBR, this would involve scanning every file. If not, it would only
require reading the bitrate and size.

Pseudo-random algorithms are hard to do well.
