Sometimes the music choice someone comes out to can really set the mood for what's about to happen. Take Price vs McDermott, McDermott enters first to a really bad Flo-Rida song, while Price enters in Liverpool to You'll Never Walk Alone. Not only is that a great song, it's a great song for the setting. The reaction for Price was pretty sensational considering the level of boxing being watched, and Price didn't disappoint his crowd with an early K.O.
Another classic is Micky Ward coming out to White Snake - Here I Go Again, which many speculate was a bitter remark on his lack of support from major networks, usually a journeyman. I'm certain the list goes on and on for great or significant introduction songs.
Recently in passing on this board (I can't remember who, or what about) but I think possibly Chisora's intro song was denied and changed... Are there other controversial intros there were outright denied? Any significant/awesome intro songs? And any songs you think would be great to come out to for a specific boxer?
