upcoming resume feature

so, if i understand, any song/mp3 put in applicable folder will resume when accessed again?  what about playlist–resume?

this would mean a no-limit bookmark feature.   

Its intented for Audio Books or Podcasts.

Playlist resume is not implemented.  If you put MP3 files in the Audiobook folder they can be resumed. 

Audiobook folder?

I have listed:

Albums

Music

Playlists

Record 

Service

Do I need to make one or is it generated somehow? 

appropriate folders , including for podcast , will be generated w/new FW update
