Finding "popular" songs IS the problem.. everyone uses them .
In addition, why would anyone choose music that is incorrect for its dance display ( Routines by Pros perpetuated this, but its gradually changing ).
Latin music has a " sizzle " that is missing from other styles.. there are even jazzy latin songs that will give a nice blend of the 2 styles of music, songs by bands like Machito and old 50s Puente .
another to check is Boogaloo, a fusion of sounds that really makes impact.
This topic,really reflects the lack of musical knowledge by many Profs in my industry.. they are stuck in a "time warp ".. and yes, I know music is subjective.. and if you believe that , then get with the subject at hand .
