Rhythm games have certainly been keeping the tempo up for financial growth in the industry. GameDaily notes UBS analyst Ben Schachter's report, showing "music-themed games" have made up 15% of software sales year-to-date and 32% year-over-year growth so far.

The Guitar Hero franchise is already up 82% this year, with Guitar Hero: On Tour taking in $15 million in July alone. Meanwhile, Rock Band, across all platforms, took in $47 million in July ... and that doesn't even count any DLC sales. Unless the rhythm game bubble bursts in the next few months, GH: World Tour and Rock Band 2 sales -- along with their respective DLC sales -- could make up a significant portion of another record-breaking year for the industry.
