My current bout with insomnia has me up at 3AM learning songs off of every cassette tape in my house. This morning I broke out a Paul McCartney tape and learned Silly Love Songs. I was amazed at how simple, how memorable, how great that bassline is. When people think about that song they think about the bassline - at least bassplayers do.... What other songs have really simple, yet great, catchy, memorable basslines in them. Or what songs do you think became popular because of their basslines?
