OK, so I purchased an audio book on CD (Elon Musk biography actually). I used my computer to "rip" the audio CDs to MP3 and then loaded that onto a USB drive, naming the files Disc_01-Track_01.mp3, Disc_01-Track_02.mp3, etc. One thing that happens is most of the tracks run longer than they show they will, but I think that my ripping system must have done some sort of variable bitrate. Not sure if that is related. The big problem I am having is that every morning when I get in my car the track that starts up is many hours ahead of where I left it. For example, I was listening to Disc 1 Track 12 and the next morning it is on Disc 8 Track 2 (or something like that). It almost seems it was playing sequentially the whole time I was gone. I have tried pausing it when I park but it doesn't change anything. Any suggestions?
