That's right folks, we can now resume our playlists from any song (unfortunately not from point of pause/stop).
It's quite simple.
1. Turn on your (in my case, H340) DAP.
2. If not in "Music" section, press and hold 'record' (circle) button above [A.B]
3. Once in music section, press [A.B] once (to view list of playlists).
4. Select Playlist (Up/Down and then NAVI or PLAY to select).
5. Playlist begins playing from start of playlist.
6. Enter your file tree navigation (during music playback, push NAVI once (if DB Scan is switched ON, push NAVI twice).
7. Scroll/Navigate to the last file you were listening to (when you paused/stopped playback).
8. Press [A.B] only ONCE to queue the selected track (will return to playback screen).
9. Wait until song finishes, or press >> (FF or skip - for those with different dialects).
10. BINGO!! Enjoy resumable playlists in all of their yummy goodness.
NOTE: Feel free to jump, scream, party, send me gifts, you know, whatever

NOTE: Obviously this works for H3xx's, my friend has a H10, and I believe she can view her playlists (contents) anyway - not sure though.
NOTE: The bigger one's are appreciated (i.e. $50, $100, etc.)
