Shuffle = Random?

Alright. Something weird is going on here.

My iPod is set to shuffle and tons of bands. Hundreds of bands have been transferred to it. The have names beginning with every letter in the alphabet.

So, how come so many “M” bands are coming up? My shuffle is stuck on M. That doesn’t seem so random. You name it: M. Ward, Mount Eerie, Mountain Goats, Mugison, Múm, Mice Parade, Microphones and Menomena - I have heard two songs from each of those bands in the last hour, yet I have everything released by A Hawk and a Hacksaw on my iPod, and nothing all day. Ditto for Okkervil River and others.

Is this an example of that handful-of-pennies-dropped-on-a-grid phenomenon?
