Cheers Garry. However it hasn't completely fixed the problem. I heard two tracks by the Beatles close together and then two by David Bowie in the last hour (2 - 3pm).

The only difference was the artist descriptions were "Beatles" and "BEATLES" and then "David Bowie" and "DAVID BOWIE". Maybe the Veronica Supergold playlist generator treats capitalisation of artist names as different artists even with the same spelling.
