with this drive you can choose the frequency range your system plays. please select at least a 10hz range (example 28 to 38) to get a good variety of tracks, if you choose a range larger than what will fit on the drive i will start from the lowest frequency you choose and go up untill the drive is full, so this means you may not get the full range you select but the drive will be as full as i can manage
 
when you choose your range you are choosing by the lowest frequency in the tracks, there may be higher frequencies in the tracks than what your selected range is
 
the usb will be made using the edits i currently have in my lineup, i will not add specific tracks
