Thanks Tony, I was aware that insert would insert after a previous insert. I assume that once the next song comes on, this insert after a previous insertion mode will not happen. Correct?

Now that I have it on my desk at work, I have been playing with it some more and it seems to be doing the right thing. I don't know what was going on in the car. Perhaps I was suffering brainfade after fighting my way through 45 minutes of traffic this morning.

For the moment I'll put it down to brain fade and I'll see if it happens again.

Thanks
