Acidic Lament

Big thanks to Aleksh for the art! IMPORTANT NOTICE; READ THIS THOROUGHLY: THIS MUSIC IS NOT IN THE NORMAL CALAMITY MUSIC MOD. YOU WILL NEED A NEW MUSIC MOD, TITLED "CALAMITY MOD EXTRA MUSIC" FOR THIS THEME TO PLAY DURING THE EVENT. Fun fact: this song is actually quite old. It was originally for Calamity itself, but then it was scrapped and I didn't know what to do with it for a while until CEM started. I've had this song pent-up in my songs folder for a while now, and I'm pleased to finally be able to release it!
