What's up Ruthless.
Not all beats need a lot of extra stuff going on, but if you talking about the beat I commented on I can tell you what I meant personally (just my opinion though).
If you take 4 bars and loop it, after hearing 16 bars or so the beat gets a little too repeatitive. So what I meant was you have a nice melody going on for you, you just need something backing it every so often like on the 6-8th bar you can bring in some strings or something for a few bars and then take them out just to add some change to your beat. Or you can add some percussion, just really anything to give it some extra flavor. That's by no means a rule just my opinion. Also, let the chorus section of the beat be known "this is where the chorus goes", if ofcourse you have that in mind. Some beats get away with being repeatitive, just depending on the beat and even then you can probably hear some subtle things going on.
I'll jump on my keyboard in a few minutes and put a little something together just to show you what I'm talking about... Give me 10-15 minutes I'll post it.
