Unneeded. I think that 2% of rap is good. Cunninlynguists, Atmosphere, etc. But what he's talking about (akon, tpain) SUCKS. Not just in a musical sense (complexity, cliche, melody), but also in the sense that it isn't even entertaining to listen to. And this coming from someone who listens to beyonce and lady Gaga. Yeah, you can argue that music in and of itself cannot be bad, but I will argue that most of rap, and even the artists I listed above, are guilty of being cliche, repetitive, uninspired, and mechanical. I'm not close-minded to any one genre (except late 80's surfer punk), or a purist of any one genre, but you have to admit that this shit isn't good and our standards have fallen. We've come from the Beatles and the Stones to Hendrix to Pink Floyd and (ugh) Led Zeppelin, and then the 80's (enough said), and then Nirvana and Jeff Buckley, to this. It's sad, and it's amazing how low we've fallen as a society when you see how we call this stuff "good" in the context of musical history as a whole.
And don't give me that "Oh, but wyatt, there are so many great Indie bands out there." Stop it. 99% of indie bands will never be heard from again after they put out their 2 shitty albums with their 4 good songs total that only sound good because they're better than the crap on the radio, which isn't saying much. Hell, even Animal Collective only has a handful of good songs; like 5 at the most. The Smiths? Like 5 good songs.
It may be a cut above the rest, but that's not saying much about the band, unfortunately. That's saying something about the industry.
DOWN WITH AUTO-TUNE.
