I'm a newbie to BiaB and I've got all the styles (the UltraPak.) I purchased BiaB so that I don't have to write a drum, bass, keyboard and fill track in Cubase or RealBand every time I want to practice a cover tune. But looking through several thousand styles to find the right one isn't exactly a thrill either. Perhaps an example would help show my problem. This is a tune by Tinsley Ellis, and I want to practice the lead guitar:

So I figure it's Even 8's, and the tempo is 50. It's blues rock. What now? There are no relevant styles that go down near tempo 50, and even if I pick styles with a tempo of 65, I can't find anything that's even close to this. I assume I'll have to use tempo 100 to get something usable. If someone could tell me which style to use (drums, bass, rhythm guitar and perhaps a Hammond) that would be nice, but then I'd be stuck on the next tune that's a little off the beaten path.

What I'm more interested in is the process that you BiaB experts would go through to find the right style. How do you narrow it down from 2000 styles? Patience folks, I'm peddling fast as I can! I've been through most of the manual, but the manual doesn't tell you how to figure out something like this.
