I liked that cover too, but The Marshmallow Song so traumatized me (previous to this convo - I saw it on a screen I happened to be sitting in front of at a... restaurant? bubble tea parlour? I didn't know who the singer was) that I haven't dared to look up more of her stuff. My tolerance for cute/twee is high but my tolerance for burikko is extremely low. XD; If it's not representative I'll check out the rest.
