I've added dpm to this review. It sounds like the following would still be acceptable to your solution:
format: translateMe("<b>%1</b> songs played today")
Clearly that would still require the translations to be updated, but it'd also avoid the natural language for plurals issue. But if the direction for all apps using the infographics will be to use the same workaround, then the Music app should follow.
