When we had home games in high school, varsity players could play an intro song over the PA.

I went with the intro to The Salt in Our Wounds- Thulsa Doom Remix by HIM.

I was super-heavyweight, so I was always the last match. That was my final-boss theme. I thought I was such a badass.

Edit: my best friend at the time, who was undefeated since 8th grade, went with the choral part of the greatest man who ever lived by Weezer. It was funny every time.
