Scratching,mixing or whatever has its place.For me its in the world of hip hop,new rnb,etc.The soul records i'm interested in are just fine and dandy the way they are,in the main.
Here's a thought for radical NS dj's.Why not just "mix" in an Instrumental and vocal track.Boom! your very own extended mix.
Or better still ...leave well alone.
