Random songs that get stuck in your head and swirl round and round, despite you not really liking them or listening to them recently. Ruby by the bloody Kaiser Chiefs is one of mine and they played a clip of it! Thanks for that BBC. The theme music from Changing Rooms has been stuck in my head since the mid-90s, I probably whistle it once a day at least.
