Autotuned songs can sound good, just as non-autotuned songs can sound bad. I'm as much a music elitist as anybody, but thinking that you have the one true objective idea of what music sounds good or bad is just childish.
I wonder if in 20 years time it will sound incredibly dated, much like 80s synths do today.
I'm not particularly against auto tune and ultimately most people don't even notice it being used, but I do sort of understand where the GP is coming from.
If your idol can't actually sing, and you saw them live and it's rubbish, wouldn't you feel cheated?
I personally dislike it too, but I'm not going to say it's not artistic, because to someone else it might be. People get so caught up and passionate with their art of choice that they sometimes forget that it's all just entertainment in the end. Whether it be Hillary Hahn or some teenager making beats in Ableton and throwing in the stock vocal effect.
About 80s synths, I think a lot of us, or at least I personally associate that cheesy sound with mass-produced digital synths put out by Yamaha, Roland etc. It's all variety and I love it. My dad still has a DX7 and a D-50 that I'm hoping to inherit.
Well just look at the status quo of popular rap music then - tons of artists are aiming for the obvious autotune style and tons of people are listening to it (so I assume they think it sounds good). I'm not sure what you mean by "artistic", but it's definitely a sound people try to achieve on purpose in their music, so I think it does deserve some recognition as "art".
