Jim Johnston is still the music guy for WWE and in recent years, it's been hit or miss I guess. Sheamus' theme is perfect (Kofi's is good, too). Others, not so much (Cody Rhodes, Sin Cara).
TNA's music is crap, too reminiscent of the basic, droll WCW themes (with the exception of a few....Sting, nWo, Goldberg, Harlam Heat, Horsemen).
For example, I know Hogan's TNA theme is a rip of the nWo music....but to me, it sounds too similar to Eddie Guerrero's WCW them. lol
Punk personally chose Cult of Personality and pretty much forced WWE to pay a lot of money to license it.
