I'm on Starlight Stage!!
As the title says, I just recently started playing Idolm@ster Cinderella Girls; Starlight Stage. It is a Music/Rhythm game very similar to Love Live: School idol Festival, with cute collectible idols and a huge list of songs to play. If you are a fellow player you can add me through either of my IDs:

PS: If you live outside Japan, but you are interested in playing this game use QooApp. Just make sure that your device can install apps through sideloading. (Google it)
Below are screenshots of the Home Page and song selection screen:
