Jukebox issues - I've solved most of my juke box issues by using DW Jukebox. This is a dedicated bit of software and suits my needs better. It still shows the file names rather than the MP3 info but I'm hoping to work out what I've done wrong. I'll recommend this program though as it was very easy to set up.
AtomicFE / mame issues - it seems it's treating any new screen as a music list rather than a game list. My game screen properties showed MP3 folder which is obviously wrong. I deleted the screen and created a new games screen but it's still showing MP3 folder in the properties and it isn't asking for the mame emulator address

I've been through all the menus etc and haven't seen anything to alter this. I'm a bit stuck.
