I have used BIAB for the foundation of the song especially for styles I don't play well, and then remove strings or bass or redo drums to my liking. If you use it as a tool and not simply as a finished product you can produce your own music and sound more professional. To do that, you need to be able to edit and play midi which if you are serious about your craft is worth learning and all those piano lessons become important. Without keyboard skills it makes it very difficult to get there. To build a song in a daw from scratch is a lot of work, which is how I do most of my songs, where BIAB will get you there faster, again you need to learn the program and as much music theory you can to get a good result. Or get someone to do some tracks and you build on it from there. Today's software, I use the latest Cubase pro, which include good drum tracks to insert and edit at will, and the plethora of sounds makes only one midi keyboard necessary to produce a great sound except in some older analog needs.
