pattern in randomness?!!

smarts. connects my mp3s to my speakers and plays. then set at random and mug (i like listening to songs at random mode). for 1.5 hrs, from a playlist of 93 songs, i see three damn farny trends:
1) i get 2 songs playing 3 times. yupz. rocks, rite? esp the one wif dang ni. play dang ni. then play yuan dian. then play dang ni again. lol.
2) most of the songs seem to come from a s'pore female singer, namely joi chua, although she only has abt 10 songs in my mp3
3) for 1.5 hrs, i did not hear a single liang jing ru song. considering tt she has abt 20 songs on the mp3. yupz. then abt 1/2 hr after i realised that, the mp3 played one of her songs. and another one. and another one.........

i swear that the mp3 was set in random and all the songs by the same singer were all over the place, scattered all within my mp3. yupz. interesting patterns of observation. in fact, the mp3 has just ended the liang jing ru streak wif chi pang. lol. now i noe wat to do for re nxt yr if i dun make it for ldp. randomness in mp3 players. who wants to join me? xD
