Here's a useful tool to mass download songs

I'd recommend downloading all the ranked songs and working your way up the star difficulty scale. So download only ranked songs, sorting by difficulty and then enter something stupidly large 300+ whaterverthefuck. A song being ranked means that it has passed quality control and isn't an unplayable piece of shit.
