This, less the 'after having their music written for them by actual musicians.'
Disturbed for instance. I personally love Disturbed, but have any of you heard them live? The lead singer struggles at best to pull off 1 show. You can tell by watching/seeing a couple performances that his voice is captured at different points and edited together. Simply because he can not pull off his bitchin vocals most of the time. The difference is they make a GREAT studio band and a mediocre live show. That's my opinion though.
Iron Maiden, Bruce Dickinson, perhaps he gets some touch ups in studio to his vocals but 90% of the shows they do he sounds pretty dead on to his recordings. All due to his actual musical talents, his vocal talents. He does not require effects to warp his vocals into some tunnel sounding crazy chorus effects. They make a great show, and would still sound dead on with minor sound stage set-up. That's what makes great musicians. Oh and btw, bands switching up live, changing their songs a bit, that's normal, that's the freedom you get playing music, you can PLAY with it =) Never has to sound the same.
Kanye West, and EVERY other 'artist' that warps their vocals with chorus and multiple other (someone said earlier) robotic sounding effects is crap imo. Was it Little Wayne, idk, too many 'artists' these days are making shit tons of $$ off more studio effects and less talent. And rapping to me is not singing, it's rapping, totally different. And I will not deny that it takes talent to be a good rapper. But you are not a singer, and you are not a musician. You're a rapper. Skills to slap together some lyrics telling a story while making sure to rhyme now and then to keep the flow going.
People now-a-days need to pay more homage to the Rush's, Maidens and even Journeys out there. That my friends is music and real talent!
Personally I think those with more simple minds grab hold of a lot of these shitty new artists, not to sound mean and I'm not trying to demean anyone, this is just my outlook. The simpler the music, less intricate and less technical the simpler the minds are whom enjoy it.
As far as Kanyes outburst goes, I already said I would have loved to see someone trip that fucktard as he walked towards that stage. He deserves no less than to be made to look like the twat he is.
