Music Player Problem. (?)

i know that my mom will buy me anew phone this month. but i'm really curious about my current cellphone, this started a month ago. my music player has limits! *yea sounds funny
it can only play 25 music files from my 1gb memory card.
but when i bought it last november 2007 it can still reach upto what number of songs i have.
WHY?

oh, and my phone's 3110c
tytyty

yah i saw it already it looks great. but i told my mom to buy me 5610 xpressmusic, LOL i like it so much. )
