I still have no idea what this show is, but the mere fact it's from PA Works is enough to have me drooling with anticipation. Hanasaku Iroha was wonderful, not to mention the superb animation work they did on Angel Beats.
That said, if it was some mahou shoujo anime or something I probably wouldn't watch it anyway. But "Slice of Life, Daily Life, Music" sounds very promising. Hopefully they're actually accurate, and not just someone's guess - since I can't see where those tags came from.
