randomising tracks: scripting question

[Frank Shute]

I generally play my tracks of an album like so:

for track in $(cat trombone_shorty-backatown.m3u); do
mplayer $track
done

They then play in the correct order.

How would I go about randomising the order of play using
sh (preferably) or perl?

Sorry for the OT posting but I thought a brainteaser might clear the
fog caused by excessive Xmas indulgence ;)
