Having the README list how to download everything in every format would make it impossibly long.

Have you tried passing the -f mp3 option on the command line?

Readme is not supposed to cover with examples just any possible usecase. Nonetheless it contains enough data to figure that out on your own. Needless to say this was asked numerous of times one should only bother to use search.
