It would be a lot better if CCP played “Emergency Beat” in the background every time someone engages in pvp combat. It would make the game a lot more lively.
I shazamed “Emergency Beat”, when I heard it in the background of a TV show once. Later found out it was once the theme song of WWE. According to Shazam, the company that owns the album (“Dramatized”), the sound track is part of is called, VideoHelper. According to them in their description suggested usage scenario, it says one of them is “Intense Battle scene”. Which according to Wikipedia is company that helps television channels in getting background music into their shows. So it probably would cost a lot less, then asking for a song that was made by a regular singer or composer.
Edit: Changed it from any normal combat to pvp combat instead.
