I was gifted a bootleg copy of Miyazaki movies from Amazon back in like 2012/2013. Two movies to a disc with poor quality rips. I've been collecting the official blu-ray releases at a rate of like 1/year at this point. I just noticed today actually that there's a 2017 blu-ray release of Castle in the Sky with the expanded score

I actually think it was this one or something close to it https://www.amazon.com/Studio-Ghibli-Complete-Collection-Miyazaki/dp/B005C67YAQ/ref=sr_1_7?ie=UTF8&qid=1530038626&sr=8-7&keywords=miyazaki+collected+works
