Dusty Rhodes, and Hulk Hogan are probably the favorites. Tazz's theme from ECW was hard as fuck, I love that theme. Christians music from WWE fit him so perfect. Of course Edge's theme right now is awesome, as was the rob Zombie theme he had. I actually downloaded MVPs theme music, and its actually a pretty tight song, it has a weird baseline to it tho, but he does have one of the better entrances. I always used to think the Broods music was cool lol. My favorite right now, which they fucking REFUSE to use, is Triple H's King of kings. got that on a cd, I fuckin love that song, I dont understand WHY they dont use it, it fits the gimmick, and him, and he has had the same music for ages.
the weakest ones are the ones they give the generic wrestlers. DH smiths music right now is generic and gay as fuck. Shelton Benjamins music automatically makes me not want to take him seriously, it sucks soooo fuckin bad lol.
Also honorable mention to Ted Dibiase. Honestly that might be the sickest music of al them, I just picked Hulk and Rhodes over it, becuase they usually were accompanied with huge crowd pops, which enhanced the entrances, especially with such energetic music. But Dibiases music just fuckin OWNED period lol
