The Style Picker Category has a few of those. Do you know about the dropdowns in the Style Picker? The 'Show Style by Feel and Tempo' is very handy. Below that is a dropdown to show only Midi, Real, or both styles. Once your feel and tempo are set, these can really help narrow down choices.

Personally I have about 5 customized styles that I use in all my songs contained in My Favorites. Getting to that point was tedious as I had to audition as you described. By using the dropdowns, it made it a bit easier. Something I discovered is the tempo range of the style often works just fine outside of that range. I guess with RD/RT tempo swapping the suggested tempos are not applicable. But even with some Midi/RD styles, outside of that range works fine. Keep that in mind.
