I realize there are plans for Performing, but in the meantime stopgaps are important. 3.0 has given me an extra 300 ranks, and now there's nothing that gives me "slightest hint of difficulty" anymore. Any chance of a more difficult instrument or just a more difficult song type?

Without knowing anything about the coding involved, it seems like adding another song type would be the easy solution, since there wouldn't be any descriptions to write. If so, please give it a whopping difficulty, so that it can be milked for a good while by starting with easy instruments and working my way up to harder ones.
