Wondering if there is there a definitieve thread on file formatting / exif etc for WM-1a WM-1z ????? Never really had a problem, dropped a bunch of files to it, by simply opening up in folder after conecting the USB to my MacBook Pro .. open "music" then drop acording to music / artist name /...

Sounds facinating, personaly would love to be able to side swipe between album art / VU meters ;-)

Hey Lookout 57, are you refering to the "Battery Care" Settings / Device settings / Battery care ?

OK I have used it to auto-off where it went black while listening. however will run it to auto-off and then plug in and let it do a full charge in one sitting. I think I have already, but have expereinced "calibration issues" on other devices before, so worth a try. Thinking if not successful...

Hate to ask this.. but broke down and picked up a WM-1a. loving it.. BUT.. getting about 3-4 hours of battery life playing .FLAC's at proabbly 75-80% volume, screen off in 1 minute.. This seems short? Bo
