A few that I think are perfect and should never be changed:
Everyone one of those guys themes has impact, straight away you know something is going to happen, just from the entrance music.
Zigglers will definetly change in time, as will Cesaro / Barrett.
I like your list. I would agree with the all. I liked "perfection", a little bit better than "show the world", but they are really similar. I also like Cesaro's theme it has that foreign heel vibe to it. Barrett's song is just awful.
All the Divas have horrendous entrance songs. Kaitlyn is one of the worse. What are they thinking?
I highly recommend you guys checking out some TNA entrances. They have some good ones. Booby Rhoode's entrance reminds me so much of 2000 triple H.
Of course their theme "fit". The only lyrics are "We're the 3 man baand!". But don't you think it is a bit to simple? It feels like the music department just mashed something together during lunch, when they came up with theirs
