In a nutshell - experimenting with things that don't appear compatible on first look. You never know. Take any of the tracks included with the BIAB product and click onto "styles". Pick a style at random and then apply it to the BIAB track you selected. It doesn't always work out well, but more than half the time I get something interesting or that can be reworked into a pretty decent song. I posted half a dozen, or so, songs on the showcase forum that started out that way. One of them (Dead End Rendezvous) has become one of my favorite originals.
Just some thoughts, FWIW.
