For a while it was Suzie Q for me. Then I decided to change my attitude and took to looking at the crowd for that song. I had enough brainpower leftover to play the song, and thoroughly check out everyone in the crowd.
Repetitive songs are a pitfall, you can get caught in a trap of sleepwalking through them. I try and avoid that now and think of other things I can do when I have brainpower to spare during a song, like work in a twirl, or check out the fleshy parts of the babettes, make eye contact with people, smile, anything to entertain myself.
I mean what kind of attitude is it when you don't want to play to a certain song? As long as the crowd digs it that's enough for me.
