u/Alive-Passenger-2620

Sorry if this is a dumb question. I for some reason can't figure out how to put in playlists into rockbox to listen to. I have an ipod nano 2nd gen with 8gb of storage set up with I think rockbox 4.0. I have the .m3u files ready but when I click a song in the "Playlists" tab it just shows the song name and creator, the time just stays at 0:00 and it says the song is 0:00 minutes long. I have all the music in a folder called "music". Is it supposed to be on the root of the drive or somewhere else? I have my .m3u files in the playlist folder if that helps at all. Any help is appreciated, thanks a bunch!
