Recursively Play MP3's with mpg321/mpg123 and find

It's really easy.

Sorry for the unscheduled post, but I've got to stick my head out of hiatus for a second to beat a few brows.

Long story short, I was Googling find (trying to learn how to write ballsier one-liners) a few minutes ago and stumbled unto a bunch of random threads on various, unrelated sites where people were stroking out about how mpg321 and mpg123 cannot easily play MP3 files recursively.

Basically, these chumps were doing this: 

toconnell@chevette:/mnt/data/audio/Soutaiseiriron$ mpg321 *
...and then whinging at the Internet about how much better whichever lame GUI solution works.

Here is a PSA for you people on how to do simple recursion on your filesystem and play MP3 files as you go: 
toconnell@chevette:/mnt/data/audio/Soutaiseiriron$ find -name *.mp3 |mpg321 -@ -
You can also do shuffle/random by adding a majuscule or minuscule "z": 
toconnell@chevette:/mnt/data/audio/Soutaiseiriron$ find -name *.mp3 |mpg321 -z -@ -
Incidentally, on most modern shells and in most contemporary Linuxes, this will auto-magically handle white space and unrecognized characters: 
toconnell@chevette:/mnt/data/audio/Soutaiseiriron$ find -name *.mp3 |mpg321 -@ -

Like, check it out computer-hacker-guy: you live on the command line now; in case you haven't figured it out yet, the whole damn thing is series of lists. Get hip to working with lists or GTFO.
