BTW, a RMS measurement (and there a tons of different way to do this) is only loosely related to perceived loudness.
Both correlate to a certain amount, but there's no causality between them.
For example, a 10Hz sine at full level will roughly hit -3dB RMS - but it's neither really audible nor really loud. On the other hand, a 1kHz square wave at -12dB RMS will blast your head away (just an example).
It's even worse, inharmonic noise always sounds "louder" than pure tones (sine waves) and there are many other factors regarding "loudness" a simple RMS meter can't handle.
Don't base your decisions on measurement tools you don't understand. Use your ears and common sense, that's all you really need. Or at least take the time to read about all these meters and what they really do.
More loudness will not give you any kind of competition benefit. It's even the opposite, broadcast doesn't play squashed material (because it sounds ugly through their own loudness chain), DJ don't feature squashed tracks in mixes or club-nights because they are neither funny to mix, scratch or dance to and sound super ugly through the P.A. and most serious music customers deeply hate it.
Music needs room to breath. Music is all about contrast. Don't fvck it up by blindly squashing something to certain numbers.
NOBODY LIKES TO READ FULL CAPS TEXTS. THEY POP UP QUICKLY, BUT IMMEDIATELY BECOME BORING AND IRRELEVANT. IT'S THE SAME WITH MUSIC. WORDS LOSE THEIR SHAPE, THEY ARE MUCH HARDER TO READ. YOU'RE STILL READING ME? YOU SEE WHAT I MEAN? NOTHING KICKS ANYMORE, IT'S NOW IMPOSSIBLE TO CREATE FOCUS OR TO HIGHLIGHT ANY PASSAGE.
Something like THIS IS much more EFFECTIVE. Don't you think?
Loudness is highly relative, your track needs both low-level and high density to surprise the listener (i.e. impress him with sudden loudness).
