I sing to myself in my head. Tonight it was "On the sunny side of the street" as sung by Willie Nelson on his Stardust album. 'Cause the honeysuckles are in bloom right now, and they made me think of the movie Honeysuckle Rose, but I don't know any songs from that...

For really hard rides I play good riding music in the car for about a week beforehand, so it will be stuck in my head during the ride.

One time I spent several hours singing "Fight On, Pennsylvania," which is the fight song for the college I went to. It worked quite nicely.

One day last year I sang "Ice cream and cake and cake. Ice cream and cake and cake. ICE CREAM AND CAKE DO THE ICE CREAM AND CAKE!!!" from the Baskin Robbins commercial that I saw just before leaving for the ride. I did this for about 35 miles.
