Taiko no Tatsujin: The Drum Master!

To get a Silver Crown you must simply clear a song. You can still miss, but don’t try to miss a lot of notes. If you miss too many notes you’ll fail and won’t get a silver crown. Keep scoring until the bar on the top right is in the yellow. Easiest to do “HOMURA” on easy difficulty found in the anime category.

Update (Thanks to VixyNyan for letting me know):

This achievement doesn't stack with the Gold Crown one, so you have to play a song once again to attempt the Silver Crown.
