i use my flash drive to play music on my truck stereo. problem is i havent found a way to set the order i want to listen to them. i see that it will put the newest songs to the end but there are two new songs that i put on that wont switch places. the one i want to play first always plays second. i even put the one i wanted to play last in the trash and ejected the flash drive and reloaded it put it puts it in front of the one i want to play second. ay thoughts on this.
