That's pretty much what a producer is these days, at least in the hip-hop genre.
The whole "skill" pretty much comes from having a good ear and resources to look though, then access to equipment. That's it.
I'm not complaining though. Even though the amount of work may be questionable, the outcome - the ability to hear a sound or vibe in a different, moderncontext - is really all that matters.
I'd rather be listening to a simple loop with some extra drums rather than some cheap sounds thrown together that sound like garbage.
When it comes to saying "I could do that," I think that statement pertains more to the Soulja Boy, Bay Area, etc. type production rather than thesample-based side of the genre. It may seem easy once you have a sample to work with, but finding that sample and using it effectively is more complicated thanreusing the same 808 sounds in different patterns.
With that being said, the Ignorant S--- beat, even though I love it, is a little too simple from a production standpoint. Just thought I'd though that out.
