Im guessing it refers to a regular 4/4 beat.

This is pretty much the standard beat for all trance music.

It means:

x---x---x---x---
--o---o---o---o-
----@-------@---

where x is your kick, o is your hat, @ is your clap, etc.

Of course this is just a generic example. Basically anything in 4 4 time with a kick on every downbeat.

4 to the flloor means kik mbadd kik bass kick dass jick drunk, scott project tile
