Listen to the chorus!! At 0:54 Isn`t he playing dead, and those chords he anticipate behind the beat?? I listen those chords that changes on the 4+ more lazy than those that lay on 1.. I am right????? This is from a session guy of Argentina his name is Guillermo Vadala one of the best bass players of soputh america. I think it is a very simple line, but a very good example of how to groove those straight 8ths...What do you think??
