I'm a BIAB addict too! Love PGMusic and all their programmers. Amazing software for sure. They also have great customer support. I use several backing tracks from BIAB on my gigs. Here are two examples of backing tracks I built using BIAB - it's so much fun to take a guitar player from one style, and combine it with a keyboard player from another style! Here is my track for "It's Impossible":

Here is a track I did with BIAB for "Desperado":
