Once you get past the hot air and out of context tweets, a 'mixdown' is a process to make each layer of your music – i.e. drums, bass, melodies and vocals – sit well together so that your track sounds the best it possibly can. It's a bit like arranging a family seating plan to stop any fights kicking off.

Start with the most important sounds – drums (starting with kick and snare, then bring in the rest), then bass, then chords, vocals and backing instruments. Bring them in one by one from the fader zero position. As each group enters the mix, you'll be acutely conscious of it and hear it in greater detail.
