I also have music on my memory card and the way I get it to show on TF is when you are on the music tap on TF, hit the library menu and scroll to the right to the six tap which is the one that looks like 3 discs one on top of the other. Here you will select unknown genre and that's where you'll see it and just make it play one of them and you'll be able to browse to the others on TF.
