I don't know about BIAB writing a hit song, but there isn't a day goes by that I'm not inspired by BIAB to compose an original tune.
It's usually something I hear while trying out different styles that sparks the beginnings of an original melody and chord progression.
Sometimes even the lyrics as well.
I honestly don't think I would write near as many songs with out BIAB as my inspiration.

I've never tried the automatic composing features yet, but keep meaning to.
Especially the automatic composing of chord progressions.
