I have looked at content with more of an open mind in the last few years and as you say, we have multi GB of free content... a lot of the "loops" are one shots.. hits, percussion, swells, stabs and can provide a great odd shaped jugssaw piece to fill a gap or transition, or can provide a launching board for a whole track..based upon the rhythmic content of a 2 bar bass loop, and some oddball drum pattern... there is a lot of trash there, and some good stuff, and a lot can be done with audio fx too.
time moves on.. there is no room for elitism in music.. it whatever works for you...Loops are a significant part of the music scene now, particulary for the younger crowd, what matters is more people are mucking with music than ever before and thats a good thing..
