Shuffle seems not so random?

I upgraded from the e200 series to the Fuze for the better shuffle feature! 

Now i have not noticed my player repeating any songs when i pick a genre playlist of like 400 songs!

I have read on this forum that the Random Shuffle mode on the player will never repeat a song on any playlist you select that is under 2000 songs!!! 

The shuffle feature does take into account user actions! For instance if you start a playlist (under 2000 songs) and listen for a while then you go to the currently playing list and find a song in the list and select it manually that will restart the shuffle and it may repeat! Even if the song you choose had not already been played!!!

But if you just skip tracks you should not have any repeats! 

If you choose to Play Previous after turning the player off then back on it should not have any repeats!

I brought all these points up you all have mentioned on this forum many months ago and that is when i learned the info i am sharing with you now! 

I am already looking at the new touch SONY because i want to have my entire library and listen to all of it without repeats! 

THe 4000 song limit for the UI and The 2000 song shuffle limit are my biggest gripes with this player everything else is great!
