FD, if you are thinking of taking the plunge, your timing is a little off. There is usually a big sale around Christmas and New Year.

I don't think you have to worry about becoming lazy and trying to get BIAB to write the song. I have never done that. I always come to it with lyric and melody already in my head, worked out on the piano or whatever. BIAB provides the backing. It also provides some surprisingly good instrumental solos. I was wary of those at first, but now I give them a shot and if I'm not blown away by them, I do it myself with midi.

I think maybe this is why the Americana demos sound good to you. The emphasis on melody and lyrics in that genre allows BIAB tracks to do their job backing up the singer. Strangely perhaps, BIAB seems to have started out with a strong emphasis on jazz and there are more styles labeled jazz than anything else.
