Can anyone describe the process/tools you use for setting master RMS levels for your songs?  
 
I've been importing my Sonar mixes into Ozone 7 standalone, then import a popular published track or two that seem in the same genre as mine, getting a sense of the loudness of the tracks and corresponding rms levels on the meters, and setting up my track to roughly match.   Due to the rms integration times available for the meters (doesn't seem to be a perfect one for me), it seems like alot of work to watch the meters and get an overall loudness idea of the song. Doesn't seem very accurate, either. I must be doing this the hard way. It works, but would be nice to do it "right".  there are probably programs out there that will do this step accurately... or am I doing something wrong in Ozone? 

This might be just the ticket - the TT-Dynamic range tool is free, and it comes with both an offline tool and a vst plugin for real-time usage.
 

SuperG...   that looks great, thanks !     Am I safe to do a download from that site?

Yes that site is well-known and has been there for many years.
 

Try TBULoudness from ToneBoosters. It will provide a loudness graph of your song.

OK, tried TT-Dynamic Range Tool offline several times (they say in the manual that the offline tool is the one to use for accuracy).....   very interesting results. Great insight into levels. Wondering how accurate this meter is.....  Anyone possibly compare it to the Wavelab analysis tool? Considering getting Wavelab elements just for the analysis features. Gotta be able to set your levels predictably, somehow...
 
I'm a little confused by this...  what is everybody with home studios out there doing for setting proper comparative rms levels for their songs in the respective genres ?  Ozone 7 basic, which I have, has nothing to tell you what your rms levels are for the entire song. You have to sit and watch the output meters, which may flick past the rms peaks depending on the integration time you set.
Seems like setting proper levels is a basic requirement for anyone producing music. 

I use Izotope Insight's LUFS meters.
 
Before that, I would export the mix to a stereo file, load it into Sound Forge, and check Statistics. That gives a good loudness analysis.

I use Bluecat's metering suite which is extremely comprehensive

I use both Wavelab 8.5 and Ozone 6.
I put Ozone in the master section of WL and check the LUFS via the meters.
There is also an analysis feature that will check your wave for loudness.
I run my songs up against references and after all that, check with my ears as well.
Keeps me very close to where I want to be.
 

Don't know it for a fact, but apparently Studio One has all this metering / loudness stuff built in...   duh!...  what a good idea !
