Usually when a cheap mic is better for the job it's a Shure SM7b or a Bluebird. Not ever a $5 toy mic. Even if I wanted a toy mic sound I would still use a good mic and then use AudioEase Speakerphone to sound like anything I want. Hollywood Undead is some "friends" of mine and they don't have the best quality sound but it matches their style and they use a Rode NT2a but it goes straight to a high end pre and a Distressor. Even when you want the sound of a cheap mic you usually run it through some great gear to properly capture that sound.
And the thing I like about FutureSex is the vocal mixes. Not the whole mix. I mean Ja Rule (don't really like his music) has some of the best sounding vocals I've ever heard for vibe, quality, mix, and smoothness and they used a U87 to a Avalon 737. And I hate the 737. But it's still good gear. I've never heard a vocal mix that impressed me and then found out it was a USB mic.
All I'm saying is that although you might get something you can live with out of a USB mic it still doesn't compare to any mic through a real mic pre and converters.
And I do believe that the chain still matters by the time it hits iTunes. Another amazing recording is Listen to your Heart by DHT. M49 mic to all boutique gear.
Name one quality recording pressed to cd on a usb mic. I'd be surprised if there is any.
