I've searched all over the place and about Googled myself into a stupor!
Does anyone have any magic answer on how to join M4B files into one? I converted all of my MP3 audiobooks into M4B so they would show up as audiobooks.
Now, I find out that on a Classic, audio books are pretty much just thrown in there all out of whack. People suggest joining all the files as one big file, so you can keep better track of it.
Also suggested was a playlist, but I haven't messed with that yet.
