I must confess I love cheeseburgers. I had a wonderful (but expensive) one in a hotel in Inverkip a few weeks ago. They must have taken a sirloin steak and minced it up just before they cooked it. I cook a fair few cheeseburgers at home as well. But I'm very picky so I cook them on a George Foreman, then cut them up and dry as much of the grease off them with kitchen towel as I can.
But not McDonald's ones

I honestly can't stand Abba music. But then again I like some music with virtually no real "musical excellence" to it, so why should that be a criteria? I think perhaps age has something to do with it. While I was born while Abba were around, I'm a little too young for them. I think when we're about 16 to our mid twenties we're very malleable to music. I think we pick up the music we like at that stage of life and it sticks with us. When I was that age I was in clubs or at raves, and as a result I can't help but like old school rave music. I'm well aware that much of it has little real merit to it. But it makes me happy.
