I was exploring the database today, and found there is a @talkingblues category with 6 songs, as well as a @talking category that has but one song. A search under talkin* blues (asterisk is a wild card that brings up everything starting with "talkin," including "talkin'" and "talking") comes up with a few false hits, but with a whole lot more talking blues songs than you'll find in a category search. There are some great songs in that database, I'll tell ya.
