I just started to use 0.25... I had a few "Unknown genre!" errors from some GH imports (done by RawkSD3). A few:
Bring Me To Life [BH] ("Industrial")
Our Lips Are Sealed [BH] ("Pop")
Semi-Charmed Life [GHVH] ("pop")
Seven Nation Army [GHWOR] ("Blues Rock")
Sharp Dressed Man (Live) [GHWOR] ("Blues Rock")
Other than noting this in the log (in red), RB DLC Manager is correctly showing the genre.
