i have an m3 simply for my ds and i have music in it.  i notice the sound quality sounds weird when you turn it all the way up and you start to heard fuzzyness or something, its not clear, and same with the head phone but on my sansa it doesnt seem to have a problem, i havent notice this before and usually i have it all the way up, is this the ds problem or the file did i break the speaker on the ds. im hoping its not the ds and if it is then my ds lite is probably a "lemon"  the screen shifts, the touch screen is yellowish, the top part of the ds lite wiggles, the gba slot cover is not tight (stick out a bit if you pull it out really really light and not even forcing it). the top part of the dsl clicks when you open it ( not _ _ but _ /) compared to my friends DSL.

when you open the dsl, it it suppose to click, my friend told me that it does it when its new but my other friend's ds lite didnt do it when it was new. 

i have so much question with the ds lite, all this problem makes me wish to go back to psp,  i never had a problem with it.
