Once something awesome happened to me, I was downloading an album by torrent and I started listening to it at 50% of the total download. It was just l0L, because torrents download in "random" parts I listened to random parts of random length of random files non-stopping, and I loved it.
So I came up with this:
let R=$RANDOM%12000+1; let T=$RANDOM%2000+100; find "$1" -name "*mp3" -type f -print0 | xargs -0 mpg123 -C -Z -k $R -n $T
This one liner generates a random number between 1 and 12001 to use as the frame from which to start playing the other random number (between 100 and 2100) of frames from a random file in the directory specified by $1 (I use it in a script, to one-line it put the directory name directly there).
I love this shit, mainly because I listen to all kinds of shit: dnb, trance, brakcore, house, techno, minimal, alt-rock, psychedelic, goa, chillout, ambient, 8bit and noise; and randomixing between this stuff creates a fucking awesome effect.
