Is iPod random

Is the iPod really random. I seem to hear the same songs over and over even though I have over 9,000 song on my iPod. The songs seem to even play in the same order.

Here is a list of songs I recently heard and I'm trying to see if they're played again in the same order.

What are your thoughts on this?
1. Gimme Shelter
2. Nothing Compares 2 u - Sinead
3. Show Me Heaven - Cheap Trick
4. Thetan - Single Gun Theory
5. Locomotion - Grand Funk
6. Mother's Talk - Tears for fear
