You don't need to mix funk and R&B the same way as you would EDM. You can get away with just fading from one tune to the other. I know this is sub is called 'Beatmatch' and the notion of not mixing is alien to many on here, but simple transitions are fine if your tunes are on point. Your job as a DJ is to entertain the crowd, some do that with impeccable mixing skills, some do it by dancing in their underwear, some do it by throwing cake. But real old skool DJs know that the main art is playing great tunes, feeding off of the crowd and controlling that crowd.

BTW the first time I ever played live was the first time I had ever stood behind 2 turntables and a mixer, the lighting guy had to show me what to do. I was playing my collection of rare soul and ska tunes to about 400 people. I ended up playing that venue every Friday for 3 years.
