I find that if I have a song idea that consists of a "playalong track" it is much faster to just play that track into RB, send it to ACW to extract the chords and tempo, then start adding additional tracks (either with Realtracks or my own playing.) Doing this I usually end up with something that sounds close to what I had in mind.

When I start in BIAB the end result ends up sounding more like the selected style... and it can be really time consuming to audition 2,000 styles to see which one is closest to what I envisioned.

One key element to getting exactly the sound I want is the drum beat... and in RB the drum grid that enables the creation of a custom beat in minutes really helps to sculpture exactly the cadence I had in mind
