As for 'auditioning' styles, I just download the style to the KB and play it a few times, at various tempos, and try to 'hear' a song it will fit ... once I have chosen a song, I will 'tweak' the style - perhaps change/add/eliminate voices or parts, whatever, and if I have changed the style to fit a particular song, I will save the style in a USER section and rename it to the name of the song ...
