Only a non-game person can make a statement like that...Meaning that sampling, using stock loops and libraries is just another part of the stash a BEATMAKER has in his arsenal!
Let's just get into some facts:
The best things in rap, hip hop, pop and any commercially driven style of music, are the ones that have the IT factor - GENIUS SIMPLICITY... Best example is THE POLICE - EVERY BREATH YOU TAKE (right now is in the 20 best royalty checks in the whole music Game! Number one is the HAPPY BIRTHDAY shyt!)
I've been making music since 1997 and YES i do use stock loops! I am not a greatly piano or guitar player! I use to be a drummer so my strength is the groove, but at first i was just downloading some shyt and never botherd to pay for it! As much as i got deeper in the producing game i started to purchase libraries, so that i can use them commercially, and of course to appreciate the work of the person who made them! Eventually back in 2000 i said that i am always gonna try to create my own drum groove, play as much as possible, or program as much as i can! Just to feel happy on the inside about my creative level! Bu the pace changed, the libraries changed...If you make beats now you know - some sites have such a bargain that for a 100 bucks you wiil have material to sample, replay, reuse, or rearrange for years to come...And most of the time played flawless and by great musicians!
You have to also know how a producer/beatmaker caries himself about these things...
I don't consider myself a producer as a level, because i really think great producers carry a GOD like aura in this music business: THEY CAN RECORD AND CREATE A WHOLE NEW SOUND FOR A DRUM SET, RECORD FREAKIN OCHESTRAS AND EVEN READ THE MUSIC THAT THEY ARE RECORDING!
So exposing somebody seems like something childish! Kanye wants to be compared to Bethoven, but that's silly and stupid! These guys are in a easy jenre and as soon as they switch the drum game or play with the tempo and sample something that's not so regular for hip hop they are called GENIUSES! The real geniuses are the ones behind the boards! Most of the time these new cats is just beatmakers! They come up with a great idea all wrapped up in a muddy mix, bounce the tracks to somebody who really produces and the shyt becomes a diamond after the great ears of some music GOD touch it! Just ask somebody who worked with the great hip hop artist about the original mixes they we given by the beatmakers!
So it's just one big circle and personally i think that most of the cats in music right now should be just humble, because most of the shyt that's hot right now is just old recycled shyt and the real geniuses were living in other times, even in other centuries! Watch a documentary on Pink Floyd for example, especially if you delved into their music and know how innovative they were! Watch a YOUNG GURU interview and hear how they make 5 master versions for all the different platforms in hip hop, so that the song fits perfectly for radio, tv, internet and etc...
So about the loops - Loop is just a loop, you can't make a career and be a great producer of of one loop, but if you got the ear and the years of experience, you'd know that you got a diamond in the rough that need a lil polishing! So you buy the shyt, use it, i'd even recommend to play with it, switch the tonality a lil bit, play with the tempo and go rock with it! The game don't have the time and money to make you sample guitarists, piano players, string sessions or whatever, because everybody wants a hit yesterday! But when you get the big money, that's when you have that dough to really make a unique sound and be a ZIMMER, then you can start the real creative process!
