Random Nonstop not so random?

I say this because lately I've gotten some really coincidental sets. For example:

-Silent Hill, Silent Hill 3rd Christmas Mix, White Lovers (all Xmas songs);

-Paranoia Rebirth, End of the Century, Don't Stop!, Silent Hill (all some of the oldest DDR songs);

and this one was the weirdest... I got, in this order:

-Burnin' the Floor, Burnin' the Floor Momo Mix, Still in My Heart, Still in My Heart Momo Mix.

I've seen people get two or more Max or Paranoia songs in one game several times, or two different versions of other songs right in a row, like Higher.

What do you think? Have you ever had any weird song packages?
