I am looking for the name of a song or artist. I have heard the song played at NFL games, NBA games, and college basketball games this year and last year. It's usually played at kickoff, tipoff, or after timeouts to get the crowd and players pumped. It?s a techno/hip-hop song. It sounds like a group of people shouting. And the group sings/shouts (read fast) ?oh, oh, oh, oh, oh (pause) oh-oh, oh-oh, oh-oh.? Then it repeats.
