A lot of hip-hop producers use samples of vinyl crackle loops to add that special something to their beats. Some people say it's cheating, and some don't give a rats ass. I don't care myself, and I use any samples I can get my hands on, as long as the end result sounds good.
I found a nice little one dollar sample pack on Tradebit, which has 50 different (long) samples of pure, unadulterated vinyl noise. Funnily enough, the pack is called "Vinyl Noise"!
