I was playing a D-League game and my team was up by 3 when the other team called a timeout. Coming out of the timeout I think the song Sirus was played (the song the Bulls uses during their starting lineup presentation). I've heard the beginning of the song before, in normal NBA games, when it starts with a low "rumble", then the guitar and bass drum comes in. Always thought it would be cool if it was Sirius, but I never reflected on that it could actually be that song, and I've never been able to hear it clearly because of the announcers.
I'm not 100% sure, but I'm 95% sure it was that song I heard.
