@ Lasse Lammert
You are so right!
Mastering for some means LOUD levels, where it should be about psychoacoustic check and relative level check and rms check and what you can bring to the track to make it shine even more than what the mixing engineer did with the original mix.
But we all know that anyway.
There are no real orders to master a track, this is the truth but, the basic are normally around that; EQ,COMP,Limit;
But sometimes a tracks might demands for more so then you could use a slight touch of stereo imager, Mid/Side Eq'ing, Reverb, Parallel compression, name it.
Sometimes a Limiter does the job, it depends of your source and how well it was mixed, but it all depends.
