Speaking of bad music at top level comps, my teacher played me a few of the new #1 Latin songs that are being played at Euro comps. Good thing I'm not good enough to cross the pond: they were totally techno-crap...
And then there was a samba (WDSF 2011 World Youth Latin, http://www.youtube.com/watch?v=CMT59J6AQDs, jump to 6:16). At that point all I could hear was SEX, SEX, SEX ON THE BEACH!!! I later found out that it was a cocktail, but still...hated it.
And, the chachacha in the same video goes on about "getting funky" with that very not-latin beat, then switches to a very pure latin, and then goes back again...HTTN!!!
