A Particular Correspondent noticed that the previous version of Play Random Album was biased towards larger albums when selecting one at random. The problem was that it grabbed a random track first and built the album out using the album of that track. Well, of course. Albums with more tracks had a better chance of being selected by virtue of having more tracks in the pool, as it were.
The latest version of Play Random Album actually chooses a random album name first which gives every album a fair chance. I've also speeded it up a little and tweaked some error checking. Attach it to a keyboard shortcut and it almost feels native.
I just bought a set of Bose 201 speakers and I've been burning 'em in (ahem, letting them experience a variety of frequencies) by playing random albums using this script. Works great.
