I'm a DJ that likes pretty underground house and techno. Most of the vinyl I purchase isn't available in any other form, and will tend to be made in a limited quantity. I find that this creates much more memorable performances that make them stand out from others. Vinyl's fun to DJ using turntables but I can't say the same with CD's. They're just inconvenient and I'd rather use an USB that stores more files. I think there's also a pretty big myth around vinyl sounding better, which might contribute to the popularity of it.
