No idea how this happened, apart from I've had loads of issues with my laptop and itunes (and everything else computer related). All started when I fried the lappy with a chinese takeaway spillage, but having spent alot of money on it decided to have it fixed. It works but not always in the way you imaging, even with the most cynical view of MS Windows. Also my daughter used it a bit because, being young, she downoads stuff rather than buying real things and then, being young, doesn't have everything synchronised on every piece of electronics she owns - and then had a disaster losing one of these bits of ephemera, and realising I'd bought her some stuff I still had acces to it. Consequently there's some gear in my itunes library I wouldn't touch with a barge pole. Anyways I digress. For some reason I had umpteen 'on the go' playlists I didn't know I'd created so thought I'd delete them all. But going through one in particular stood out - Wise Baby Dreams by Glide, AKA The Sarge, followed by Son of My Father by Chicory Tip. And that's it. Works quite well.
OK I'm procrastinating with the clear out, but you know.........
