Okay i found something cool i don't know if many other folk have found it.

Q up a playlist and start playing it then go to another playlist using the front buttons then hold the bottom button down and a wee menu appears with "insert replace append" select append and the second playlist is queued up after the first playlist.

I love this thing

A point for all the newbies joining us i have had this thing for over a year and new things still pop out of the woodwork.
