I hope Nagareboshi he has a song. And that there's a decent range of SeraMyu pieces. I'm kind of sad but not entirely surprised that La Soldier hasn't shown up in the new Myu yet, so maybe here~. I was also disappointed that we didn't get Nagareboshi he in the Anniv. OST, but I'm hoping they're saving it for a single of its own for the Crystal adaption of Stars.
Hopefully they'll focus on the more popular songs, but also ones that haven't gotten much love yet since the anniversary stuff. Some of the new Crystal songs would be nice too.
Depending on what they go with, I'm kind of excited to buy the inevitable CD~.
