Like it. These street-dancing cultures are the last great repositories of innovation in music these days, aren't they? (Saying that, they are musical forms which nick all sorts of ideas from rap/rnb/dancehall.) Juke, Bop, and now this...
Please post examples of the psychedelic use of autotune in dancehall.
I think in rap music there's still an expectation of being able to understand lyrics (no matter how simplistic) which sets limitations on auto-tune.
Young Thug is obviously pushing that to the limit, and has attracted all sorts of opprobium because of it.
Or perhaps it's just a more conservative genre than dancehall, which seems to be driven by this constant competitive and innovative imperative?
I would have instincitvely tied in autotune in rap with increased use of drugs (lean, xannies, etc.) - what is the drug use like in dancehall, I wonder?
Finally, it must be said that autotune, for most rappers, has simply opened up an avenue for them to sing without seeming like wussies.
