Thanks Malc ..

Unfortunately I don't have the tracks ripped to the Laptop, I've just been inserting the CD's in and downloading the track listings into OCD. When I do a function (strictly part time, mostly friends and family) I use a Double CD player and mixing desk, so I'm not using MP3's at all.

I want to use OCD simply to know exactly what tracks I have available and what disc I can find them on.

So I guess it's just plain old fingerwork then... ;-)
