There are so many millions of records out there, you should always be playing old and new together. This way, people can respect what the early elders of certain musical tastes have given to what we are now, and where we're going in the future. I don't care if it's rap, metal, whatever. You still should play Beatles records mixed with Limp Bizkit mixed with Foghat mixed with Creedence Clearwater Revival, stuff like that.
