I have a sansa e270 with a 2 gig micro sd card in the slot. Question... is there any way to play the entire library in the sansa randomly? Like the original sansa firmwear allows you to? I have a lot of music and I use the sansa (8 gigs at a time) to edit it down to a master play list. Is there a way to save a playlist and its associated files only, then dump everything else and reload it with new music and continue to edit it down to the saved play list? Is this a suggestion for the developers or am I just misreading the manual.
