I think I can cover this one.
All three of the examples you've stated have absolutely no bearing on how your ballet is judged; I recall that these are some specific items that new judges are admonished to ignore because they are subjective. I can even feel certain that if someone DOES let such criteria creep into their decision-making process and word gets out, that person will not be judging again.
To address each item individually:
From day one we are told to fly to the music WE like, music that has opportunities in dynamics, tempo changes, etc. Your choice of music isn't being judged, how you fly your kite to INTERPRET the music is.
Judges are also told not to consider lyrics used in a ballet track, only the music. From me to you; if you've got a good song in mind where the instrumentation can stand on it's own, edit out the vocal track. Objectional lyrics should however be avoided as a courtesy to spectators (both of them ).
Comps are not turf battles between sponsors, they are neutral territory. A truce is in effect. Picture this; you would fly NIB, so your panel might be made up of the Machine, Viper, Sea Devil, a couple of STX2.3's, and a tastefully modded Nirvana. You (Air Ouvre) might be flying AGAINST CdC, Prism, BMK, NTK, Premier, and maybe a borrowed Instigator. If the wind is approaching the high limit you might even be flying against a Mirage. The only thing you need to be concerned with is you flying your kite better than everybody else does theirs. THAT'S what counts in the judge's eyes; not what you fly but how you fly it.
