The styles are categorized by genre, tempo etc but there is a lot of sorting and listening to be done. Like the EZs, if you like something you can designate it a favorite for later recall and use. That is helpful.

And there is usually going to be a big difference in result between someone using it with no personal experience with a musical instrument versus someone who has some. Musical ability matters when you are making music no matter what the medium and tools.

Personally I dont start a song with software. I start with a rhythm guitar and rough vocal as the skeletal structure and make a scratch track to build around. After I get the accompaniment instruments in, I may or may not keep the original guitar.
