If KI sold sheet music from their Wizard101 and Pirate101 MMOs, they would be unique to other music varities played, such as school bands. Not only the musical players of these KI games be jubilant, but would also advertise the games for free. Well, negative free since you not only gain money by new players that will join, but as well as the sheet music. The unique style and etiquette of the graceful music would certainly make judging scores good and parents of school band kids happy. But let's not leave it to only school bands. Solo piano pieces would be quite impressive. Also, I hear other video gaming companies have symphonies perform their music, but let's not get off topic. Music I suggest you guys publish to start: Commons Theme Ravenwood Theme Starfall Sea Theme Olde Town Theme Marleybone and Wysteria Music
