(BEWARE SPOILERS) Ending's meaning?!

Does the director just want us to come to our own conclusions about whether or not LANDS is still around? At the end, Asako is just standing there singing along as she watches Natsu rehearse an old LANDS song. Is it supposed to be open ended? Because the small logical part of me wants some closure. What happened to LANDS? Did Natsu go solo? Does anyone have a take on what they concluded the ending to be?
