--the point is youve spent the time digging to find the right sound. youve earned that sound to chop or loop or whatever--
also - the first OG producers to loop records were -- and i could be wrong here -- marley marl or biz markie, that is to say the first ones to make beats out of looped samples as opposed to backing bands replaying the popular disco breaks or just using drum machine sounds. they didnt do it cos they couldnt afford a "band" -- they did it because they were waaaaay deep in the crates as its always been a hugely vital important part of hip hop music. people used to steam off the labels to their breaks records at block parties so no one else would be up on their shit!! that element has always been a part of hip hop. Biz markie has still got one of the worlds most insane record collections -- he has another house to store it in, if legend is to be believed!!!!
Alright, you bring up a huge point and you are probably right; the OG producers most likely do feel the same way you do. However, I have to say I disagree...diligently digging does not (in my opinion) make you deserving of the sound (I know that is very contradictory to what most hip-hoppers feel). Does the sound, loop, chop sound any better/worse/more-unique if you dug really hard for it? I don't think it does. What does make a sample sound shitty, better/worse more unique is the producers ability to flip it and make it their own. That is why I personally don't give a shit where the producer gets their sounds from (CD, LP, MP3, whatever). What I care about (a characteristic that usually comes with [people like Pencilface] record/digging aficionados) is a genuine appreciation for the artists/tracks that they are sampling, because it's those artists that made your shit so special; their shit that you are sampling.
And I know I'm falling away from the initial topic, but I hate when people are all secretive about who they are sampling (understand that I realize that clearance issues are NOW a huuuuge deal with why that is done today....but it wasn't the case back in the Marley Marl Biz Markie days). I think it's bullshit that someone would hide the name of the artists that make their sound soooo fucking hot because they want to claim it as their own. Simply because they dug and found the record? That justifies them NOT giving proper recognition to the original artist? Nah, I've always been a fan of the Q-Bert/ISP way of doing things; share everything, bite everything and (again) do it in a way in which, eventually, (arguably, naturally) you will evolve into your own sound.
So, I guess, after all this rambling on my part, I have to stick with my feelings that the format of the sample is irrelevant to me, it's simply if you are willing to have an appreciation of the sounds/genres that you are sampling and, most importantly, if you are really trying to make your own sound, your own good music.
